Kilt

It's all in perfect working order", "The future of bonnie Scotland" or, "Shoes and socks". This most likely stems from the fact that it is just not a safe thing to do. Good standard replies if asked are, "Nothing is worn under the kilt. This is especially true in more rural areas where carrying a pocket knife is as common as carrying a set of keys. Thus, the reply to a question on the topic may hint at the answer, but rarely states it outright. In many places in the United States it is considered bad luck to hand an open, folding blade knife to someone. Whatever decision is made, what a gentleman wears under his kilt is traditionally his own business, and as a rule, polite men will be at pains to keep it so and to preserve the mystique. The puukko is always presented handle first as a sign of trust and friendly intentions.

In the end, whether or not underwear is worn on any particular occasion is up to the individual wearer. This is especially true in Finland where various non-governmental organizations, clubs and even government agencies traditionally give a puukko (a Finnish fixed-blade hunting/outdoor knife) as a gift to trusted employers or contacts. Both one of the oldest kilt makers and the oldest mail order company for Highland attire in Scotland provide underwear designed for the kilt, although most wearers who regularly go with underwear choose ordinary briefs or boxer shorts. In some cultures giving a knife as a gift is considered a sign of respect and trust. In certain instances, underwear may be useful; it is often difficult for someone new and unused to wearing the kilt to remain decent while regimental, especially in a heavy breeze or while dancing. Stirring liquids or powders with a knife is considered unlucky; as the rhyme says, "Stir with a knife, stir up strife". In 1994, a Black Watch soldier received wide press exposure, because of windy conditions during a military ceremony in Hong Kong. It is common to include a penny, often taped to the blade, with a knife given as a gift which the receiver is to return as "payment".

(This is similar to the American military expression of going "commando".) In the 1950s, kilted soldiers on parade would be checked by the sergeant major using a mirror on the end of a stick. To avoid such ill luck, the receiver should give a coin in return so as to "pay" for the gift. As a result, to go without underwear is often referred to as "going regimental" or "military practice". In some countries it is traditionally believed that the giving of a knife as a gift to a friend will cut or sever the relationship. The uniforms worn by members of several military regiments mandate "no underwear" with the kilt except at specified occasions, such as playing in the pipe band, where marking time can involve raising the knees, taking part in organised sports like Highland games, or attending functions where ladies are present. Knives can be sometimes be customised to the user and/or application:. The majority of wearers have their own preference, and usually have no qualms with whatever anyone else wears (or doesn't wear) beneath their kilt. Folding knives with locking blades are not considered pen knives and are currently a legal "grey area".

Thompson¹ claims that he never knew of a man who gave it a fair trial that ever went back to wearing underpants with the kilt, and suggests wearing a long-tailed shirt or undershirt to sit on. A special exception exists for penknives (pocket knives) which are legal without reason for possession. Then there are those who say that underwear should never be worn, and to do so goes against tradition. Sikhs). Some believe that underwear should be worn at all times, and going without it is a form of self-indulgence or even exhibitionism. sgian dubh), or if it is carried for religious reasons (e.g. The wearing of undergarments with the kilt is a matter of debate. chefs) or if it is part of a national costume (e.g.

With some ensembles, a fly plaid is added in the form of a pleated cloth in the same tartan as the kilt, cast over the shoulder and fastened below the shoulder with a plaid brooch. It is however legal to carry a knife if there is a bona fide reason to do so (e.g. When the kilt is worn as formal wear, a black "Prince Charlie" jacket is usually prescribed. In general, knives carried in public places are legally considered to be offensive weapons and the carrier can be charged with "possession of an offensive weapon". This is often in tweed. In private almost any kind of knife may be owned with the exception of automatic knives (flick knives, balisongs, switchblades) which are under any circumstances illegal. The Argyll jacket, often in tweed, is sometimes worn with the kilt, for those occasions that would usually require a sports jacket or lounge suit. Knife possession is only legislated in public places.

Shoes are usually leather brogues, sometimes with open lacing. include court buildings and federal property (the latter of which technically has a limit of 2.5 inch blades). A small knife called a Sgian Dubh may be worn in the the top of one of the kilt hose as part of the standard clothing worn with a kilt. Other restricted areas in the U.S. A decorative silver kilt pin adds weight to the loose bottom corner of the kilt. In some metro areas such as Washington, D.C., going into office buildings or museums, or simply loitering, carrying even small 3" folding knives can be problematic. Originally this was a soft deer skin pouch, but with the development of military uniforms elaborate hard leather sporrans came into use, often with decorative silver tops and white hair facings with large tassels. Cities have ordinances further restricting these laws; in San Antonio, TX, it is a violation to carry a folding knife having a locking blade.

As a kilt has no pockets, it is worn with a pouch called a sporran. In some other States, fixed-blade knives are banned, open carry is banned, and sometimes concealed carry of anything except pocket knives is banned. One of the major selling points of these garments is that one does not have to be of Scottish descent to enjoy the "freedom" and ventilation of wearing a kilt, or to offer comfort of an unbifurcated garment to men who are not aware of such a garment in their individual lineage's culture, which can include sarongs in the Pacific Islands, kimono in Japan, the thobe in Arabia, the lungi in southern Asia, and more recently, the männerrock (men's skirt) in Germany. In Texas, for example, individuals may carry knives openly or concealed so long as they are single-edged, and are not daggers, switchblades, or gravity knives (balisong legality is questionable — there have been convictions). Their products often include revisions of the traditional kilt design, often with pockets, symmetrical pleats, lower waistlines mirroring modern trouser waistlines, and a variety of fabrics and patterns. Knife laws vary tremendously. Around the turn of the last century, several companies—including Utilikilts, Twenty-First Century Kilts, and Pittsburgh Kilts—began producing garments that are often not tartan, and referring to their products as kilts. The knife laws of different countries vary, but are generally strict in Western countries.

The English county of Northumberland also possesses a tartan, and some Northumbrians, most notably Northumbrian pipers, wear kilts. Even small knives are forbidden on all commercial airliners and are among the illegal imports that may be confiscated at airports by customs staff even if packed in luggage. In these two Celtic regions the kilt is closely linked to the Celtic revival movements of the 19th and 20th century. Even multitools like the SwissTool, Gerber multitools, and Leatherman multitools are often frowned upon, due to their having relatively large blades and/or locking ability. Kilts have also made an appearance in Wales and Cornwall for special occasions. Most Western European nations are very unfriendly toward all knives other than small pocket knives and similarly small tools, which are nonetheless not allowed on planes or in certain other venues. While these garments may be disliked by traditionalists, they provide evidence that the kilt still has a place in the modern fashion world and continues to evolve. One exception is Austria, where civilian possession of automatic knives including double-edged automatic OTF ("out The front") daggers is allowed.

Solid colours have also been used in place of tartan (solid kilts were historically common in Ireland, especially saffron-coloured), as well as camoflage patterns. Balisongs (butterfly knives) are only slightly less stigmatized, and tend to be treated as switchblades by law enforcement agencies due to their connection with gang activity. Since the 1980s, kilts have appeared in such materials as leather, denim, blends of polyester and viscose, and acrylic. Automatic knives (switchblades) are almost universally banned from civilian carry if not possession. As with any other form of attire, the kilt is subject to the vagaries of fashion. chef's knives). Kilten skirts for girls are also worn. Exceptions may be made for hunting knives, and for knives used for work-related purposes (e.g.

The kilt is traditionally for men only, although in the modern era, women have also taken up the kilt as well as dresses patterned after kilts, and women pipers frequently wear kilts. Carrying knives in public is forbidden by law in many countries. Nowadays a lighter weight of cloth tends to be used. (These thoughts were stimulated by an article posted on rec.woodworking.). The modern tailored kilt is box-pleated or knife-pleated, with the pleats sewn in and the lower edges reaching not lower than the centre of the knee-cap. It has the same relative shape for any depth of cut. The small ornamental Sgian Dubh dagger may be omitted. A wedge shape has the property called "scale invariance".

Or it can be a little more dressed up with woolen kilt hose, a button up shirt, sweater, and perhaps even a sport jacket. On the other hand, if the type of use cannot be predicted, it may be better to sharpen it to a wedge and let the first use bend the edge to an appropriate curve. Casual use of the kilt can be dressed down with black boots, white socks rolled down to the top of the boot, perhaps with a black tee shirt. Perhaps this sheds light on the function of razor straps and on the practice of using two angle guides to sharpen a knife. It's not uncommon at all to see kilts making an appearance at Irish pubs, and it is becoming somewhat less rare to see them in the workplace. This contrasts to the usual practice of trying to sharpen knives to a wedge near the edge. Kilts have increasingly become more common around the world for casual wear. This is a (microscopic) parabola.

Although a white tie style exists, the more common style of formal Highland regalia is seen in Black tie. So, in this case, the ideal cross section is proportional to the square root of the distance from the edge. Kilts have become normal wear for formal occasions, for example being hired for weddings in much the same way as top hat and tails are in England or tuxedos in America, and the kilt is being worn by anyone regardless of nationality or descent. (That explains the strength per weight of aluminum, compared to steel.) If the force is applied at the edge, the bending torque is proportional to the distance from the edge. In particular, the ferocious tactics of the Royal Highland Regiment led to their acquiring the nickname "Ladies from Hell" from the German troops that faced them in the trenches. Both the area taking the force and the lever arm converting force to torque are proportional to thickness, so the bending resistance is proportional to the square of the thickness. Scottish troops last wore kilts in combat during WWI. Sheets of material are bent by stretching the outside or compressing the inside.

The ban remained in effect for 35 years, as part of King George II's campaign to destroy the traditional way of life throughout the Highlands. Assume the knife is thin and the force is applied at the very edge. In 1746, after the last Jacobite campaign the "Dress Act" outlawed all items of Highland dress including the new kilts (with an exception for army uniforms). Making some simplifying assumptions about the forces and the knife edge's ability to resist them may shed some light on ideal sharpening. These regiments opted for the modern kilts for dress uniforms, and while the great kilt remained as undress uniform this was phased out by the early 19th century. In this case the knife should resist bending or breaking. As a means of identification the regiments were given different tartans. If a knife is used as a scraper or encounters hard particles in softer materials or is used asymmetrically, there may be a sideways load near the tip.

In doing so they formed effective new army regiments to send to fight in India, North America, and other locations while lowering the possibility of rebellion at home. Realigning the edge goes a long way in keeping the knife sharp, as often times, a rolled edge will make an otherwise sharp knife dull. After 1745 the Government decided to form more Highland regiments for the army in order to direct the energies of Gaels, that "hardy and intrepid race of men". This fine process can effect alignment of the edge. From 1624 the Independent Companies of Highlanders had worn kilts as government troops, and with their formation into the Black Watch regiment in 1740 their great kilt uniform was standardised with a new dark tartan. Other times the final step is done with a steel. The small kilt developed into the modern tartan kilt when the pleats were sewn in to speed the donning of the kilt. It is useful when a knife is still sharp, but has lost that 'scary sharp' edge from use.

"The Early History of the Kilt" and "Reconstructing History" quote modern scholarship disputing this story with reference to earlier illustrations of the small kilt. It will not cut the edge significantly, but produces a very sharp edge with very little metal loss. This is the first garment that can truly be called a kilt as we know it today. This is traditionally done with a leather strap impregnated with abrasive compounds, but can be done on paper, cardstock, or even cloth in a pinch. This kilt is in the possession of the Scottish Tartans Society. Stropping a knife is sometimes a finishing step. The first instance we have of the pleats being sewn in to the phillabeg, creating a true tailored kilt, comes in 1692, before the time of Rawlinson. Rather expensive are sharpening blocks made with corundum.

It most likely came about as a natural evolution of the belted plaid and Rawlinson probably observed it and quickly deduced its usefulness in his situation and insisted on introducing it among his workers. Coated hones, which have an abrasive, sometimes diamonds, on a base of plastic or metal are another kind of hone. There is some suggestion of its use in the early 17th century, and it was definitely being worn by the 18th century. There are better ways than oil to clean a hone. The word is often spelled phillabeg in English. This is generally bad to do during polishing. If the widths are not stitched together and only the bottom 4 yards are worn pleated and belted around the waist, the resulting garment is called the feilidh-beag (little wrap). Oil is sometimes used to lift the metal dust, called swarf, off the stone.

The belted plaid consisted of two widths of material stitched together. Oil is not to be used on these. The problem with this potential source is that there are numerous illustrations of Highlanders wearing only the bottom part of the belted plaid that date long before Rawlinson ever set foot in Scotland. Generally, these are more costly than oilstones. Rawlinson required his workers to wear only the bottom part of the plaid, which for some is sufficient proof that an Englishman invented the modern Scottish kilt. They are stored in water, and develop a layer of slurry which dulls the edge if you hone the blade as if honing into the stone. His workers all dressed in not a cloak, but the belted plaid. Water stones (both artificial and natural) come in very fine grits.

Indeed, An Englishman named Thomas Rawlinson opened an iron smelting factory in the Highlands around the year 1730. Ceramic hones are also common, especially for fine grit size. Rawlinson liked the new creation so much that he began to wear it as well and was soon imitated by his Scottish colleagues, the Clan MacDonnell of Glengarry. India is another traditional source for stones. Rawlinson took this back and then introduced the new kilt. Arkansas is a traditional source for honing stones, which are traditionally (though a poor practice) used with water or honing oil. The tailor responded by cutting it in two. Honing stones (also called whetstones) come with coarse and fine grits and can be hard or soft describing whether the grit comes free.

He supposedly brought the Highland garment to a tailor, intent on making it more practical. If you feel a little bit of pull at the edge or the nail is sightly abraded, you may have a wire burr. It was thought that the traditional Highland kilt, the "belted plaid" which consisted of a large cloak, was inconvenient for tree cutters. It should come off with no resistance. After the Jacobite campaign of 1715 the government was "opening" the Highlands to outside exploitation and Rawlinson was one of the businessmen who took advantage of the situation. To feel for a wire edge, move your thumb lightly across the edge. Rawlinson was claimed to have designed it for the Highlanders who worked in his new charcoal production facility in the woods of northern Scotland. This will flip the burr back and forth as it is ground off.

A letter published in the Edinburgh Magazine in March 1785 by one Ivan Baillie argued that the garment people would today recognize as a kilt was invented around the 1720s by Thomas Rawlinson, a Quaker from Lancashire. An alternate method of removing a wire edge is stroking from side to side on a very fine stone, using light strokes. Sometime early in the 18th century the fèileadh beag or philabeg using a single width of cloth hanging down below the belt came into use and became quite popular throughout the Highlands and northern Lowlands by 1746, though the great kilt also continued in use. If not removed, it will break off in use, and the knife will instantly become dull. The kilt became part of the Scottish national identity. Use a slighly steeper angle with very light pressure to do so. King George IV had appeared in a spectacular kilt, and his successor Queen Victoria dressed her boys in the kilt, widening its appeal. Remove a wire edge (burr) if one forms during sharpening.

After that point the kilt gathered momentum as an emblem of Scottish culture as identified by antiquarians, romantics, and others, who spent much effort praising the "ancient" and natural qualities of the kilt. When you pull a knife up the V, the angle is held for you, as long as you hold the blade perpendicular to the base. At this time many other traditions such as clan identification by tartan were developed. Another variant is the crock stick setup, where two sticks are put into a plastic or wooden base to form a V shape. Scott and the Highland societies organised a "gathering of the Gael" and established entirely new Scottish traditions, including Lowlanders wearing the supposed "traditional" garment of the Highlanders. The stone is mounted on a rod and is pulled through these holes, so that the angle remains consistent. The kilt became identified with the whole of Scotland with the pageantry of the visit of King George IV to Scotland in 1822, even though 9 out of 10 Scots lived in the Lowlands. Examples of sharpening tools are the clamp-style systems, which use a clamp with several holes with pre-defined angles.

The Celtic Society of Edinburgh, chaired by Walter Scott, encouraged lowlanders to join this antiquarian enthusiasm. The composition of the stone affects the sharpness of the blade (finer grain produces sharper blades), as does the composition of the blade (some metals take/keep an edge better than others). Once the ban was lifted in 1782, Highland landowners set up Highland Societies with aims including "Improvements" (which others would call the Highland clearances) and promoting "the general use of the ancient Highland dress". In general, the harder the material to be cut the higher the angle of the edge. The kilt, along with other features of Gaelic culture, had become identified with Jacobitism, and now that this had ceased to be a real danger it was viewed with romantic nostalgia. For an extremely durable edge (such as a chisel or drawknife), sharpen to 30 degrees. Most Lowlanders had viewed Highlanders with fear before 1745, but many identified with them after their power was broken. Knives that require a tough edge (such as those that chop) sharpen at 20 degrees.

This was an age that romanticized "primitive" peoples, which is what Highlanders were viewed as. Typical knives sharpen at 15 degrees. Although the kilt was largely forgotten in the Scottish Highlands, during those years it became fashionable for Scottish romantics to wear kilts as a form of protest against the ban. Very sharp knives sharpen at 10 degrees. The heavy pleats of the Great Kilt also made for good protection from spear thrusts and sword cuts. A guide is very helpful. Use of this type of kilt continued into the 19th century. The smaller the angle between the blade and stone, the sharper the knife will be, but the faster it will dull.

The great kilt is mostly associated with the Scottish highlands, but was also used in poor lowland rural areas. Knives are sharpened by grinding against a hard surface, typically stone. Earlier carvings or illustrations appearing to show the kilt may show the Leine Croich, a knee-length shirt of leather, linen or canvas, heavily pleated and sometimes quilted as protection. However, this may also make them brittle. The age of the great kilt is hotly debated but it certainly existed at the beginning of the 17th century. Most high-quality knives are also tempered very hard, so that they will retain an edge longer. For battle it was customary to take off the kilt beforehand and set it aside, the Highland charge being made wearing only the léine. Either use is likely to break off the tip of the blade, or to bend or break the knife beyond repair.

The solid color kilts of the Irish were also usually soaked in goose grease to make them waterproof. Most knives are not intended as pry bars or screwdrivers. A description from 1746 states:. Steel blades rust easily, but oiling will prevent pitting due to oxidation and tarnish. It was worn over a léine (a full sleeved garment gathered along the arm length and stopping below the waist) and could also serve as a camping blanket. A knife should be kept clean, dry and sharp. The upper half could be worn as a cloak draped over the left shoulder, hung down over the belt and gathered up at the front, or brought up over the shoulders or head for protection against weather. Conversely it can be argued that what is dangerous is not knowing how sharp a knife is and thus how much force to use.

The great kilt, also known as the belted plaid, was an untailored draped garment made of the cloth gathered up into pleats by hand and secured by a wide belt. Also, a dull or damaged knife will inflict a worse wound than a relatively 'clean' cut from a sharp knife. The Breacan an Fhéilidh or Féileadh Mòr was originally a length of thick woollen cloth made up from two loom widths sewn together to give a total width of 1.5 m, up to 5 m in length. Dull knives lead to excessive use of force to cut materials, increasing the chance that the blade may slip and the force will be transferred to an unintended destination such as the user or another person or object. The Scots word derives from the Old Norse kjilt, which means "pleated", from Viking settlers who wore a similar, non-tartan pleated garment. A sharp knife is often claimed to be a safer knife. The word kilt comes from the Scots word kilt meaning to tuck up the clothes around the body. Knives offered to another person should always be offered handle first.

It had long been abandoned by related cultures such as Gauls, and Scandinavians. When checking the blood circle it is best to hold the knife by the blade, otherwise you defeat the purpose. It was only with the Romantic Revival of the 19th century that the kilt became irreversibly associated with Highlanders, and in the 20th century among Lowlanders and the Scottish Diaspora. In Boy Scout parlance, an area within the radius of the arm and blade length combined is called the "blood circle". Although the kilt is a item of traditional Scottish highland dress, the nationalization of that tradition is relatively recent. By extension, assume that the knife is going to slip, and look where the blade would go. . "Always cut away from yourself" is the basic adage to keep in mind while using a knife.

The British Army and armies of other Commonwealth nations still continue to have kilts as dress uniform, they have not been used in combat since World War I. Chopping knives need blunter angles, out to thirty degrees. Kilts are also used for parades by groups like the Scouts, and in many places kilts are seen in force at highland games and pipe band championships as well as being used for Scottish country dances and ceilidhs. Slicing knives should have sharper angles, down to ten degrees. They are often worn at weddings or other formal occasions, while there are still a few people who wear them daily. 15 to 25 degrees is a good all-around angle. Today most Scotsmen see kilts as formal dress or ceremonial dress. The edge is sharpened at different angles for different purposes.

(Traditionally, women do not wear kilts, but often wear full length tartan skirts.). A good serration pattern will stay sharp several times as long as a straight edge. The kilt is associated with traditional Scottish Highland dress and, as such, is almost always made of wool with a woven pattern called tartan (sometimes called plaid). The points protect the slicing areas from nicks. The historical great kilt was long enough to drape up over the shoulder but is rarely seen in modern times. Serrations on a blade "saw" through the item being cut and stay sharp for a long time. A kilt is a man's garment that consists primarily of a length of cloth wrapped around the waist and belted; it is usually accessorized with a pouch for money (and other items) called a sporran. For whittling (artistic wood carving) a blade as short as 25mm (1 inch) is common.

Many knives are specific to a particular activity or occupation:. Some knives, such as the Scottish dirk and Japanese Tanto function in both roles. In general, knives are either working knives (everyday-use blades), or fighting knives. Knives exist in several styles:.

Knives can be categorized based on either form or function. It handles much like the clip-point. A drop-point blade is very similar to a clip point, but it features the back convexed down, rather than having a clip taken out of it. An example is a head knife, used in leatherworking both to scrape down leather (reducing thickness), and to make precise, rolling cuts to form shapes.

It is the strongest knife-shape. It's good for scraping, and sometimes chopping. This sort of blade is all edge, with no point, and a handle in the middle. An ulu (Inuit woman's knife) knife is a sharpened half-circle.

The point is actually a second edge on the end of the blade, with a total edge angle of 60-80 degrees. The edge is straight. The traditional Japanese tanto knife uses the blade geometry of (1). It is superficially similar to the points on most Japanese long and short swords (katana and wakizashi).

(6) An Americanized tanto style knife is thick towards the point. Sheepsfoot knives are good for whittling, including sheep's hooves. It gives the most control, because the dull back edge is made to be held by fingers. (5) A sheepsfoot knife has a straight edge, and a curved dull back.

The Bowie has a clipped blade. If the false edge is sharpened it increases the knife's effectiveness in piercing. The sharp tip makes the blade exceptional as a pick, or for cutting in tight places. The back edge of the clip can have a false edge that can be sharpened to make a second edge.

(4) A clip point blade is like a normal blade with the tip "clipped" to make the tip thinner and sharper. This shape is primarily used for fighting knives (daggers, bayonets) because it can cut in both directions and point in line with the handle. The idea is to make a blade that cuts in either direction, with a strong sharp point. (3) A double edged or spey blade has two edges.

Such a knife is better for slicing than a normal knife. This lets a lightweight knife have a larger curve on its edge. (2) A curved, trailing-point knife has a back edge that curves upward. Therefore, the knife can chop as well as pick and slice.

The curve concentrates force on a small point, making cutting easier. A dull back lets the wielder use fingers to concentrate force; it also makes the knife heavier and stronger for its size. (1) A normal blade has a curving edge, and flat back. There are a variety of knife blade shapes; some of the most common are listed below.

Vanadium, and perhaps molybdenum, also increase corrosion resistance. Vanadium and molybdenum are important alloy metals because they make the gain size smaller, which improves hardness and toughness. These explain its reputation for long wear (the carbides are harder than the metal) and for being harder to sharpen and not taking as good an edge as rustable, low alloy ("carbon") steel (the ceramic particles themselves cannot be sharpened easily.) The bulk hardness and toughness of stainless steel tend to be lower than those of low alloy steel. Stainless steel usually has particles of chromium (or other alloy metal) carbides.

It is corrosion resistant (though knife steel is less so than higher nickel stainless steel) because, except in acid, one of the metals or one of the oxides is always stable. Stainless steel is steel with very high (12–18%) chromium content. Stainless knife steels are high in carbon, but "carbon steel" means there is not also a lot of chromium. Knife steel has fairly low nickel content, because nickel tends to keep steel in the austenitic structure, even when cold.

The blade is then tempered by heating to an intermediate temperature for a period to make it less brittle. It is formed as it is quenched, changing it from the austenitic structure that it has at high temperature to a hard, but brittle martensitic structure. All knife steel is tempered martensite, which means that a fine-grained crystal structure with lattice irregularities that make it hard. Some manufacturers, particularly of kitchen knives, make ceramic blades; these are harder and stay sharp longer, but because of their brittleness, chip and break more readily.

Forschner/Victorinox make decent, inexpensive kitchen knives; high-end manufacturers include Wüsthof, Global, Henckels and Böker (Tree Brand). There is typically more demand for exotic alloys in the utility, outdoor, and tactical or combat knife categories than there is in the kitchen knife category. The cost of the process restricts it to high-end knives. The original craft of Damascus steel may be lost, but not being a registered trademark, the name is today used to apply to the equally old but less exotic pattern welding, which creates layered and admired patterns.

All three are more ductile than typical stainless steels, but have quite a vocal support group despite concerns about health effects of cobalt content. Other manufacturers sometimes use titanium, cobalt, and cobalt containing alloys. Knife manufacturers such as Spyderco and Benchmade typically use 154CM, VG-10, S30V, and CPM440V (also known as S60V), as well as high-speed high-hardness tool steels like D2 and M2. A variety of exotic steels and other materials can be used to form blades.

Steels having high carbon but low chromium content are prone to rust and pitting if not kept dry. Chromium is the major alloying element in stainless steels, giving them the 'stainless' quality. Stainless and semi-stainless steels include D2, S30V, 154CM, ATS-34, and 440C. Tests done by Razor Edge Systems, and described in their book "The Razor Edge Book of Sharpening" indicate that stainless steel knives hold an edge better than regular steels.

Stainless steels have gained popularity in the latter half of the twentieth century because they are highly resistant to corrosion (so they usually only rust under extreme conditions). Knife blades are usually made of steel; although there are a few knives using materials like high tech ceramic and titanium, these are very uncommon. A hole in the end of the handles allows the knife to be hung or placed on a lanyard. For a large knife, it is desirable that the handle is thick enough that one's fingers just meet one's palm when the knife is gripped tightly.

The handle of a knife should be made of a non-slip material. In kitchen knives, it keeps chopped items from moving back toward the hand. In piercing, this helps keep the knife from jamming, for example in bone. See 1 Some knives also have a shoulder in which the blade thickens as it meets the handle.

Additionally, a groove on the blade can reduce surface tension between the blade and the item being cut, thereby allowing easier movement or removal of the blade. In reality, its only function is to make knives and swords lighter while sacrificing little strength; on most knives it has more decorative worth. According to a popular myth, it lets bleeding occur from an artery without removing the knife. A fuller, sometimes called a blood gutter or blood groove, is a groove on the side, along a blade.

The blade in turn consists of a tip, a spine, an edge and a heel. The bolster functions as a balance point and handguard, to prevent fingers from slipping onto the blade. The tang is an extension of the blade into the handle. A knife consists of a tang, a bolster, a blade and a handle.

. The importance of the knife as a weapon has declined as more specialized weapons have been developed, but the knife remains the universal tool. In the West, multi-purpose pocket knives are commonly carried, to be available anywhere. Today, these are not frequently sharpened, and most sharp knives are used in kitchens.

Together with the fork and spoon, the knife has been a common eating utensil in the Western world since, at least, the Middle Ages. While the materials have changed over time, the basic design remains the same. Later on with advances in smelting and metallurgy the blades were made of bronze, iron, then steel. The first knives were flint or other rock, chipped or ground to an edge, sometimes with a handle.

Knives have been used as tools and weapons since the Stone Age. The blade of a knife is usually pointed and may have one or two cutting edges. A knife usually consists of a blade, commonly less than 12 inches (30cm) in length, attached to a handle. A knife is a sharp-edged hand tool used for cutting.

Everybody's Knife Bible by Don Paul, ISBN 0938263234. The surface finish of the blade can be darkened or polished. The handle can be altered in shape (for better grip) or material (to prevent electric shock or burns).
