Knife

This most likely stems from the fact that it is just not a safe thing to do. He often remarks at shows "When I introduce myself to people, they are always surprised to learn that I'm not a guitar and I'm not dead!". This is especially true in more rural areas where carrying a pocket knife is as common as carrying a set of keys. As of 2005, Les Paul performs weekly at the Iridium Jazz Club on Broadway in New York City. In many places in the United States it is considered bad luck to hand an open, folding blade knife to someone. In 1988, Paul was inducted into the Rock and Roll Hall of Fame by Jeff Beck, who said, "I've copied more licks from Les Paul than I'd like to admit." Les Paul was inducted into the National Inventors Hall of Fame in May 2005 for his development of the solid-body electric guitar. The puukko is always presented handle first as a sign of trust and friendly intentions. He received a Grammy Trustees Award for his lifetime achievements in 1983.

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. In 1978, Les Paul and Mary Ford, were inducted into the Grammy Hall of Fame. In some cultures giving a knife as a gift is considered a sign of respect and trust. He and Colleen divorced amicably in 1964, as she could no longer tolerate the itinerant lifestyle their act required of them. Stirring liquids or powders with a knife is considered unlucky; as the rhyme says, "Stir with a knife, stir up strife". He recorded an album Lester and Chester with Chet Atkins. 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". In the late 1960s, Paul went into semi-retirement, although he did return to the studio occasionally.

To avoid such ill luck, the receiver should give a coin in return so as to "pay" for the gift. With newer digital sound technology, such an effect is available commercially. 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. He typically lays down one track after another on stage, in-sync, and then plays over the repeating forms he has recorded. Knives can be sometimes be customised to the user and/or application:. Currently he uses a small box attached to his guitar - it is not known how much of the device remains off-stage. Folding knives with locking blades are not considered pen knives and are currently a legal "grey area". Later Paul made the myth real for his stage show, using hidden equipment which over the years has become smaller and more visible.

A special exception exists for penknives (pocket knives) which are legal without reason for possession. This even became the subject of comedy, with Mary Ford multiplying herself and her vacuum cleaner with it so she could finish the housework faster (a typical joke in the pre-feminist era). Sikhs). During his early radio shows, Paul introduced the mythical "Les Paulverizer" device, which was supposed to multiply anything fed into it, like a guitar sound or a voice. sgian dubh), or if it is carried for religious reasons (e.g. His idea, later known as "Sel-Sync," in which a recording head could simultaneously record a new track and play back previously recorded ones, would further establish the future of multi-track recording. chefs) or if it is part of a national costume (e.g. In 1954 Paul, continued to develop this technology, by commissioning Ampex to build the first eight track tape recorder, at his expense.

It is however legal to carry a knife if there is a bona fide reason to do so (e.g. These records were unique for their heavy use of overdubbing, which was technically impossible without Paul's inventions. 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". In the early 1950s, Paul made a number of recordings with wife, Colleen Summers (known on record as Mary Ford). 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. Paul instructed the surgeons to set his arm at an angle that would allow him to cradle and pick the guitar. Knife possession is only legislated in public places. Paul spent a year and a half recovering.

include court buildings and federal property (the latter of which technically has a limit of 2.5 inch blades). Paul was injured in a near-fatal automobile accident in January 1948 in Oklahoma, which shattered his right arm and elbow. Other restricted areas in the U.S. When he later began using magnetic tape, the major change was that he could take his recording rig on tour with him, even making episodes for his 15-minute radio show in his hotel room. 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. Even in these early days, he used the wax disk setup to record parts at different speeds and with delay, resulting in his signature sound with echoes and birdsong-like guitar riffs. Cities have ordinances further restricting these laws; in San Antonio, TX, it is a violation to carry a folding knife having a locking blade. He favored the flywheel from a Cadillac for its weight and flatness.

In some other States, fixed-blade knives are banned, open carry is banned, and sometimes concealed carry of anything except pocket knives is banned. Paul even built his own wax-cutter assembly, based on auto parts. 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). There is no record of how few 'takes' were needed before he was satisfied with one layer and moved onto the next. Knife laws vary tremendously. He built the multi-track recording with overlaid tracks, rather than parallel ones as he did later. The knife laws of different countries vary, but are generally strict in Western countries. Paul would record a track onto a disk, then record himself playing another part with the first.

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. Amazingly, these recordings were made, not with magnetic tape, but with wax disks. 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. This was the first time that multi-tracking had been used in a recording. 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. In 1947, Capitol Records released a recording that had begun as an experiment in Paul's garage, entitled "Lover (When You're Near Me)", which featured Paul playing eight different parts on electric guitar. One exception is Austria, where civilian possession of automatic knives including double-edged automatic OTF ("out The front") daggers is allowed. Heafy and Ben Foote.

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. Les Paul guitars have been used by Duane Allman, Jeff Beck, Dickie Betts, Neal Schon, Tom Scholz, Mike Bloomfield, Eric Clapton, Davey Johnstone, Jimmy Page, Buckethead, Gary Rossington, Randy Rhoads, Slash, Pete Townshend, Johnny Marr, Zakk Wylde, Noel Gallagher, Kirk Hammett, Matt Skiba, Billie Joe Armstrong, Matt K. Automatic knives (switchblades) are almost universally banned from civilian carry if not possession. These days, Gibson Les Paul guitars are used all over the world, both by novices and professionals. chef's knives). In later years, they would change their mind. Exceptions may be made for hunting knives, and for knives used for work-related purposes (e.g. Gibson Guitar Corporation made a number of these guitars for Paul, but insisted that their name be left off of the instrument.

Carrying knives in public is forbidden by law in many countries. In 1941, Paul designed and built one of the first solid-body electric guitars (though Leo Fender also independently invented his own solid-body electric guitar around the same time, and Adolph Rickenbacker had marketed a solid-body guitar in the 30s). (These thoughts were stimulated by an article posted on rec.woodworking.). The two also recorded together several times, including a 1945 number one hit, "It's Been a Long, Long Time." In addition to backing Crosby and artists like the Andrews Sisters, Paul's trio also recorded a few albums of their own in the late 1940s. It has the same relative shape for any depth of cut. Crosby went on to sponsor Paul's recording experiments. A wedge shape has the property called "scale invariance". Also that year, Paul's trio appeared on Bing Crosby's radio show.

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. As a last-minute replacement for Oscar Moore, Paul played with Nat King Cole and other artists in the inaugural Jazz at the Philharmonic concert in Los Angeles on July 2, 1944. Perhaps this sheds light on the function of razor straps and on the practice of using two angle guides to sharpen a knife. Paul moved to Hollywood in 1943, where he formed a new trio. This contrasts to the usual practice of trying to sharpen knives to a wedge near the edge. In 1938, Paul moved to New York and landed a featured spot with Fred Waring's Pennsylvanians radio show. This is a (microscopic) parabola. This solved his two main problems - feedback, as the acoustic body no longer resonated with the amplified sound, and sustain, as the energy of the strings was not dissipated in generating sound through the guitar body.

So, in this case, the ideal cross section is proportional to the square root of the distance from the edge. For appearances he attached the body of an Epiphone jazz guitar, sawn lengthwise with The Log in the middle. (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. Famously, he created The Log which was nothing more than a length of common "4 by 4" fence post with bridge, guitar neck, and pickup attached. 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. Paul was unsatisfied by the electric guitars that were sold in the mid 1930s and began experimenting with a few designs of his own. Sheets of material are bent by stretching the outside or compressing the inside. One album was credited to Rhubarb Red, Paul's hillbilly alter ego, and the other was in the backing band for blues artist Georgia White.

Assume the knife is thin and the force is applied at the very edge. Paul's first two records were released in 1936. Making some simplifying assumptions about the forces and the knife edge's ability to resist them may shed some light on ideal sharpening. In the 1930s, Paul worked in Chicago, Illinois in radio, where he performed jazz music. In this case the knife should resist bending or breaking. Louis, Missouri on KMOX. 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. Soon after, he dropped out of high school to join Wolverton's Radio Band in St.

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. At the age of 17, Paul played with Rube Tronson's Cowboys. This fine process can effect alignment of the edge. By 13, Paul was performing semi-professionally as a country-music guitarist. Other times the final step is done with a steel. After an attempt at learning to play the banjo, Paul began to play the guitar. It is useful when a knife is still sharp, but has lost that 'scary sharp' edge from use. Paul, born Lester William Polfus (Polsfuss) in Waukesha, Wisconsin, first became interested in music at the age of eight, when he began playing the harmonica.

It will not cut the edge significantly, but produces a very sharp edge with very little metal loss. . 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. He is a pioneer in the development of the solid-body electric guitar (the Gibson Les Paul he helped design is one of the most famous and enduring models), multitrack recording, and various reverb effects. Stropping a knife is sometimes a finishing step. Les Paul (born June 9, 1915) is best known as a guitarist, and as one of the most important figures in the development of modern electric instruments and recording techniques. Rather expensive are sharpening blocks made with corundum. Les Paul & Friends: American Made World Played.

Coated hones, which have an abrasive, sometimes diamonds, on a base of plastic or metal are another kind of hone. Chester and Lester - album with Chet Atkins. There are better ways than oil to clean a hone. Les Paul Now!. This is generally bad to do during polishing. Hits of Les and Mary. Oil is sometimes used to lift the metal dust, called swarf, off the stone. New Sound.

Oil is not to be used on these. The World is Still Waiting for the Sunrise. Generally, these are more costly than oilstones. Warm and Wonderful. 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. Lover's Luau. Water stones (both artificial and natural) come in very fine grits. Swingin' South.

Ceramic hones are also common, especially for fine grit size. The Les Paul Trio. India is another traditional source for stones. "I'm Sitting on Top of the World". Arkansas is a traditional source for honing stones, which are traditionally (though a poor practice) used with water or honing oil. "Bye Bye Blues". Honing stones (also called whetstones) come with coarse and fine grits and can be hard or soft describing whether the grit comes free. "Vaya Con Dios".

If you feel a little bit of pull at the edge or the nail is sightly abraded, you may have a wire burr. "How High the Moon". It should come off with no resistance. "Lover (When You're Near Me)". To feel for a wire edge, move your thumb lightly across the edge. This will flip the burr back and forth as it is ground off.

An alternate method of removing a wire edge is stroking from side to side on a very fine stone, using light strokes. If not removed, it will break off in use, and the knife will instantly become dull. Use a slighly steeper angle with very light pressure to do so. Remove a wire edge (burr) if one forms during sharpening.

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. Another variant is the crock stick setup, where two sticks are put into a plastic or wooden base to form a V shape. The stone is mounted on a rod and is pulled through these holes, so that the angle remains consistent. Examples of sharpening tools are the clamp-style systems, which use a clamp with several holes with pre-defined angles.

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). In general, the harder the material to be cut the higher the angle of the edge. For an extremely durable edge (such as a chisel or drawknife), sharpen to 30 degrees. Knives that require a tough edge (such as those that chop) sharpen at 20 degrees.

Typical knives sharpen at 15 degrees. Very sharp knives sharpen at 10 degrees. A guide is very helpful. The smaller the angle between the blade and stone, the sharper the knife will be, but the faster it will dull.

Knives are sharpened by grinding against a hard surface, typically stone. However, this may also make them brittle. Most high-quality knives are also tempered very hard, so that they will retain an edge longer. Either use is likely to break off the tip of the blade, or to bend or break the knife beyond repair.

Most knives are not intended as pry bars or screwdrivers. Steel blades rust easily, but oiling will prevent pitting due to oxidation and tarnish. A knife should be kept clean, dry and sharp. Conversely it can be argued that what is dangerous is not knowing how sharp a knife is and thus how much force to use.

Also, a dull or damaged knife will inflict a worse wound than a relatively 'clean' cut from a sharp knife. 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. A sharp knife is often claimed to be a safer knife. Knives offered to another person should always be offered handle first.

When checking the blood circle it is best to hold the knife by the blade, otherwise you defeat the purpose. In Boy Scout parlance, an area within the radius of the arm and blade length combined is called the "blood circle". 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.

Chopping knives need blunter angles, out to thirty degrees. Slicing knives should have sharper angles, down to ten degrees. 15 to 25 degrees is a good all-around angle. The edge is sharpened at different angles for different purposes.

A good serration pattern will stay sharp several times as long as a straight edge. The points protect the slicing areas from nicks. Serrations on a blade "saw" through the item being cut and stay sharp for a long time. 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).
