Knife Folding
A knife ( : knives; from Old Norse 'knife, dirk') is a tool or weapon with a cutting edge or blade, usually attached to a handle or hilt. One of the earliest tools used by humanity, knives appeared at least 2.5 million years ago, as evidenced by the Oldowan tools. Originally made of wood, bone, and stone (such as flint and obsidian), over the centuries, in step with improvements in both metallurgy and manufacturing, knife blades have been made from copper, bronze, iron, steel, ceramic, and titanium. Most modern knives have either fixed or folding blades; blade patterns and styles vary by maker and country of origin. Knives can serve various purposes. Hunters use a hunting knife, soldiers use the combat knife, scouts, campers, and hikers carry a pocket knife; there are kitchen knives for preparing foods (the chef's knife, the paring knife, bread knife, cleaver), table knives (butter knives and steak knives), weapons (daggers or switchblades), knives for throwing or juggling, and ...

Titanium
Titanium is a chemical element with the symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the Titans of Greek mythology. The element occurs within a number of minerals, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere; it is found in almost all living things, as well as bodies of water, rocks, and soils. The metal is extracted from its principal mineral ores by the Kroll and Hunter processes. The most common compound, titanium dioxide, is a popular photocatalyst and is used in the manufacture of white pigments. Other compounds include titanium tetrachloride (TiCl4), a component of smoke screens and catalysts; and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cross Section (geometry)
In geometry and science, a cross section is the non-empty intersection of a solid body in three-dimensional space with a plane, or the analog in higher-dimensional spaces. Cutting an object into slices creates many parallel cross-sections. The boundary of a cross-section in three-dimensional space that is parallel to two of the axes, that is, parallel to the plane determined by these axes, is sometimes referred to as a contour line; for example, if a plane cuts through mountains of a raised-relief map parallel to the ground, the result is a contour line in two-dimensional space showing points on the surface of the mountains of equal elevation. In technical drawing a cross-section, being a projection of an object onto a plane that intersects it, is a common tool used to depict the internal arrangement of a 3-dimensional object in two dimensions. It is traditionally crosshatched with the style of crosshatching often indicating the types of materials being used. With computed ...

Grind
A blade's grind is its cross-sectional shape in a plane normal to the edge. Grind differs from blade profile, which is the blade's cross-sectional shape in the plane containing the blade's edge and the centre contour of the blade's back (meaning the shape of the blade when viewed from the side, i.e. clip point, spear point, etc.). The ''grind'' of a blade should not be confused with the bevel forming the sharpened edge; it more usually describes the overall cross-section of the blade, not inclusive of the beveled cutting edge which is typically of a different, less acute angle as the bevel ground onto the blade to give it a cross-sectional shape. For example, the famous Buck 110 hunting knife has a "hollow ground" blade, with concave blade faces (which aid in slicing through materials), but the cutting edge itself is a simple, flat-ground bevel of lesser angle. It would be difficult, if not impossible, to put a "hollow grind" onto the actual cutting edge of the blade itself, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kirpan
The kirpan is a curved, single-edged dagger or knife carried by Sikhs. Traditionally, it was a full-sized sword but modern Sikhs have reduced the length to that of a dagger or knife due to modern considerations based on societal and legal changes since then. It is part of a religious commandment given by Guru Gobind Singh in 1699, in which he gave an option to the Sikhs, if they accepted they must wear the five articles of faith (the five Ks) at all times, the kirpan being one of five Ks. The Punjabi word ਕਿਰਪਾਨ, kirpān, has a folk etymology with two roots: ''kirpa'', meaning "mercy", "grace", "compassion" or "kindness"; and ''aanaa'', meaning "honor", "grace" or "dignity". It is derived from or related to Sanskrit कृपाण (kṛpaṇa, “sword, dagger, sacrificial knife”), ultimately from the Proto-Indo-European stem *kerp-, from *(s)ker, meaning "to cut". Sikhs are expected to embody the qualities of a ''Sant Sipahi'' or "saint-soldier", showing no fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Switchblade
A switchblade (aka switch knife, automatic knife, pushbutton knife, ejector knife, flick knife, Stiletto, flick blade, or spring knife (Sprenger,Benson, Ragnar (1989). ''Switchblade: The Ace of Blades''. Paladin Press. pp. 1–14. . The switchblade is also known in Germany as the ''Springmesser''. SpringerShackleford, Steve (ed.) (2009). ''Blade's Guide To Knives And Their Values''. Krause Publications. pp. 151–152 .)) is a type of knife with a sliding or pivoting blade contained in the handle which is extended automatically by a spring when a button, lever, or switch on the handle or bolster is activated. Virtually all switchblades incorporate a locking blade, where the blade is locked against accidental closure when the blade is in the open position. It is unlocked by a mechanism that allows the blade to be folded and locked in the closed position. During the 1950s, US newspapers as well as the tabloid press promoted the image of a new violent crime wave caused by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dagger
A dagger is a fighting knife with a very sharp point and usually two sharp edges, typically designed or capable of being used as a thrusting or stabbing weapon.State v. Martin, 633 S.W.2d 80 (Mo. 1982): This is the dictionary or popular-use definition of a dagger, which has been used to describe everything from an ice pick to a folding knife with pointed blade as a 'dagger'. The Missouri Supreme Court used the popular definition of 'dagger' found in Webster's New Universal Dictionary ("a short weapon with a sharp point used for stabbing") to rule that an ordinary pointed knife with four-to-five inch blade constitutes a 'dagger' under the Missouri criminal code.California Penal Code 12020(a)(24):"dagger" means a ''knife or other instrument'' with or without a handguard that is ''capable of ready use as a stabbing weapon'' that may inflict great bodily injury or death. The State of California and other jurisdictions have seized upon the popular-use definition of a dagger to clas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steak Knives
A steak knife is a sharp table knife designed to efficiently and effectively cut steak. This type of knife comes in a variety of styles and sizes; however, the design often used in a steakhouse typically features a partially serrated blade and wood handle. American style Specialized steak knives emerged in America after World War II. Prior to World War I, all table knives were sharp, but required frequent upkeep—sharpening and polishing. With the decline in numbers of domestic workers, this upkeep became less feasible. Stainless steel became widespread following World War I. This did not require polishing, but did require sharpening due to manufacturing limits. After World War II, serrated stainless steel steak knives which required neither polishing nor frequent sharpening, were commercially successful. In the 1950s heat treatment of stainless steel was introduced, allowing knives to remain sufficiently sharp without needing serrations, but by this point serrated steak knives ...

Butter Knives
In common usage, a butter knife may refer to any non-serrated table knife designed with a dull edge and rounded point; formal cutlery patterns make a distinction between such a place knife (or table knife) and a butter knife. In this usage, a butter knife (or ''master butter knife'') is a sharp-pointed, dull-edged knife, often with a sabre shape, used only to serve out pats of butter from a central butter dish to individual diners' plates. Master butter knives are not used to spread the butter onto bread: this would contaminate the butter remaining in the butter dish when the next pat of butter was served. Rather, diners at the breakfast, the luncheon, and the informal dinner table use an individual butter knife to apply butter to their bread. Splint, Sarah Field. The Art of Cooking and Serving. Cincinnati, Ohio: The Procter & Gamble Co., 1930. "Table Service in the Servantless House" pp. 3-4, "The House with a Servant" p. 27 Individual butter knives have a round point, so as not ...

Kitchen Knives
A kitchen knife is any knife that is intended to be used in food preparation. While much of this work can be accomplished with a few general-purpose knives – notably a large chef's knife, a tough cleaver, a small paring knife and some sort of serrated blade (such as a bread knife or serrated utility knife) – there are also many specialized knives that are designed for specific tasks. Kitchen knives can be made from several different materials. Construction Material * Carbon steel is an alloy of iron and carbon, often including other elements such as vanadium and manganese. Carbon steel commonly used in knives has around 1.0% carbon (ex. AISI 1095), is inexpensive, and holds its edge well. Carbon steel is normally easier to resharpen than many stainless steels, but is vulnerable to rust and stains. The blades should be cleaned, dried, and lubricated after each use. New carbon-steel knives may impart a metallic or "iron" flavour to acidic foods, though over time, the ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pocket Knife
A pocketknife is a knife with one or more blades that fold into the handle. They are also known as jackknives (jack-knife), folding knives, or may be referred to as a penknife, though a penknife may also be a specific kind of pocketknife. A typical blade length is . Pocketknives are versatile tools, and may be used for anything from whittling and woodcarving, to butchering small game, gutting and filleting small fish, aiding in the preparation of tinder and kindling for fires, boring holes in soft material, to opening an envelope, cutting twine, slicing a piece of fruit or as a means of self-defense. Specialised designs are also used for mushroom hunting and gardening. Pocketknives designed for gardening include pruning knives, which are folding knives with long curved blades used for pruning, trimming cuttings, taking buds and preparing material for grafting. History The earliest known pocketknives date to at least the early Iron Age. A pocketknife with a bone handle wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
