Ballpoint Pen Knife
A ballpoint pen knife is a multi-tool pocket knife consisting of a blade concealed inside an ordinary-looking ballpoint pen. The blade, typically in length, is usually hidden. They first appeared as custom-made pens from various custom knife makers before being mass-produced by production companies. Uses Pen knives such as these are designed for self-defense due to their ease of concealment. Their small size renders them impractical as weapons in elaborate combat, but their slim profile allows them to cause great harm in close-range combat with an element of surprise. A knife of this type can be used as a standard letter or package opener. The knife can also be used for cleaning fingernails, peeling fruit and vegetables, cutting meat, and carving or shaping wood. They come in many versions, including variants with special purpose razors for shaving. Kinds of blades All ballpoint pen knives come with straight blades, which are easier to conceal than curved blades. These bl ...

Multi-tool
A multi-tool (or multitool) is a hand tool that combines several individual functions in a single unit. The smallest are credit-card or key sized units designed for carrying in a wallet or on a keyring, but others are designed to be carried in a trouser pocket or belt-mounted pouch. Historical The idea of incorporating several tools in one unit is very old, dating back at least as far as Middle Roman times. Many of these were used for eating. Pocket knives Among the earliest contemporary examples is the Swiss Army knife, as supplied by makers Victorinox and Wenger. The actual version supplied to the Swiss army includes a knife blade, a reamer, a bottle-opener–screwdriver–wire stripper, and a can-opener–screwdriver. Besides Victorinox and Wenger, many other manufacturers now make similar knives. Other versions may include items like a nail file, tweezers, folding scissors, a tooth pick, a magnifying glass, screwdriver bits and others. There are also versions ...

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] |
Ballpoint Pen
A ballpoint pen, also known as a biro (British English), ball pen (Hong Kong, Indian and Philippine English), or dot pen ( Nepali) is a pen that dispenses ink (usually in paste form) over a metal ball at its point, i.e. over a "ball point". The metal commonly used is steel, brass, or tungsten carbide. The design was conceived and developed as a cleaner and more reliable alternative to dip pens and fountain pens, and it is now the world's most-used writing instrument; millions are manufactured and sold daily. It has influenced art and graphic design and spawned an artwork genre. Some pen manufacturers produce designer ballpoint pens for the high-end and collectors' markets. History Origins The concept of using a "ball point" within a writing instrument to apply ink to paper has existed since the late 19th century. In these inventions, the ink was placed in a thin tube whose end was blocked by a tiny ball, held so that it could not slip into the tube or fall out of the ...

Self-defense
Self-defense (self-defence primarily in Commonwealth English) is a countermeasure that involves defending the health and well-being of oneself from harm. The use of the right of self-defense as a legal justification for the use of force in times of danger is available in many jurisdictions. Physical Physical self-defense is the use of physical force to counter an immediate threat of violence. Such force can be either armed or unarmed. In either case, the chances of success depend on various parameters, related to the severity of the threat on one hand, but also on the mental and physical preparedness of the defender. Unarmed Many styles of martial arts are practiced for self-defense or include self-defense techniques. Some styles train primarily for self-defense, while other combat sports can be effectively applied for self-defense. Some martial arts train how to escape from a knife or gun situation or how to break away from a punch, while others train how to attack. To ...

Scabbard
A scabbard is a sheath for holding a sword, knife, or other large blade. As well, rifles may be stored in a scabbard by horse riders. Military cavalry and cowboys had scabbards for their saddle ring carbine rifles and Lever action, lever-action rifles on their horses for storage and protection. Scabbards have been made of many materials over the millennia, including leather, wood, and metals such as brass or steel. Most commonly, sword scabbards were worn suspended from a sword belt or shoulder belt called a baldric. Antiquity Wooden scabbards were typically covered in fabric or leather; the leather versions also usually bore metal fittings for added protection and carrying ease. Japanese blades typically have their sharp cutting edge protected by a wooden scabbard called a Japanese sword mountings#Saya, saya.

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] |
Stiletto
A stiletto () is a knife or dagger with a long slender blade and needle-like point, primarily intended as a stabbing weapon.Limburg, Peter R., ''What's In The Names Of Antique Weapons'', Coward, McCann & Geoghegan, , (1973), pp. 77-78 The stiletto blade's narrow cross-section and acuminated (tapering gradually to a sharp point) tip reduce friction upon entry, allowing the blade to penetrate deeply.Atkins, Anthony G., ''The Science and Engineering of Cutting: The Mechanics and Processes of Separating, Scratching, and Puncturing Bio-Materials, Metals, and Non-Metals'', London: Elsevier Ltd., (2009), p. 214 Some consider the stiletto a form of dagger, but most stilettos are specialized thrusting weapons not designed for cutting or slashing, even with edged examples. Over time, the term ''stiletto'' has been used as a general descriptive term for a variety of knife blades exhibiting a narrow blade with minimal cutting surfaces and a needle-like point, such as the U.S. V-42 stilett ...

Serrated
Serration is a saw-like appearance or a row of sharp or tooth-like projections. A serrated cutting edge has many small points of contact with the material being cut. By having less contact area than a smooth blade or other edge, the applied pressure at each point of contact is greater and the points of contact are at a sharper angle to the material being cut. This causes a cutting action that involves many small splits in the surface of the material being cut, which cumulatively serve to cut the material along the line of the blade. In nature, serration is commonly seen in the cutting edge on the teeth of some species, usually sharks. However, it also appears on non-cutting surfaces, for example in botany where a toothed leaf margin or other plant part, such as the edge of a carnation petal, is described as being serrated. A serrated leaf edge may reduce the force of wind and other natural elements. Probably the largest serrations on Earth occur on the skylines of mountains (th ...
