A scalpel, lancet, or bistoury is a small and extremely sharp bladed instrument used for surgery, anatomical dissection, podiatry and various arts and crafts. Scalpels may be single-use disposable or re-usable. Re-usable scalpels can have permanently attached blades that can be sharpened or, more commonly, removable single-use blades. Disposable scalpels usually have a plastic handle with an extensible blade and are used once, then the entire instrument is discarded. Scalpel blades are usually individually packed in sterile pouches but are also offered non-sterile. Double-edged scalpels are referred to as "lancets".
A Bowie knife is a pattern of fixed-blade fighting knife created by Rezin Bowie in the early 19th century for his brother Jim Bowie, who had become famous for his use of a large knife at a duel known as the Sandbar Fight.
A switchblade is a pocketknife 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.
A stiletto is a specialized knife or dagger with a long slender blade and needle-like point, primarily intended as a thrusting and stabbing weapon.
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, EDC knife, or may be referred to as a penknife, though a penknife may also be a specific kind of pocketknife. Blade lengths typically range from 5 to 15 centimetres. Some pocketknives have multiple tools in addition to one or more blades.
The Laguiole knife is a traditional Occitan pocketknife, originally produced in the "knife city" of Thiers, source of 70% of France's cutting tool production, as well as the small village of Laguiole, both located in the Massif central region of France. Laguiole in this instance does not refer to the French knife brand but to a generic type of traditional slipjoint knife associated with this region of France.
James Syme was a pioneering Scottish surgeon.
A surgical instrument is a tool or device for performing specific actions or carrying out desired effects during a surgery or operation, such as modifying biological tissue, or to provide access for viewing it. Over time, many different kinds of surgical instruments and tools have been invented. Some surgical instruments are designed for general use in all sorts of surgeries, while others are designed for only certain specialties or specific procedures.
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 – there are also many specialized knives that are designed for specific tasks. Kitchen knives can be made from several different materials.
Robert Liston was a British surgeon. Liston was noted for his speed and skill in an era prior to anaesthetics, when speed made a difference in terms of pain and survival. He was the first Professor of Clinical Surgery at University College Hospital in London and performed the first public operation utilizing modern anaesthesia in Europe.
A glass knife is a knife with a blade made of glass, with a fracture line forming an extremely sharp cutting edge.
Sharpening is the process of creating or refining the edge joining two non-coplanar faces into a converging apex, thereby creating an edge of appropriate shape on a tool or implement designed for cutting. Sharpening is done by removing material on an implement with an abrasive substance harder than the material of the implement, followed sometimes by processes to polish/hone the sharp surface to increase smoothness.
A combat knife is a fighting knife designed for military use and primarily intended for hand-to-hand or close combat fighting.
Ek Commando Knife Co. or Ek Knives is an American combat knife brand produced by several different companies since the original founded by John Ek in 1941. In May 2014 the Ek brand was purchased by Ka-Bar which began selling its versions of Ek knife designs in 2015. Although not officially issued gear, Ek Knives have seen use by US forces in six major conflicts: World War II, the Korean War, the Vietnam War, the Gulf War, Afghanistan, and the Iraq War. Ek Knives manufactures Bowie-style blades, daggers, and a Fairbairn-Sykes MkII. President Franklin Delano Roosevelt, Clark Gable, and General George S. Patton have been identified as Ek knife owners.
A catlin or catling is a long, double-bladed surgical knife. It was commonly used from the 17th to the mid 19th century, particularly for amputations; thereafter its use declined in favor of mechanically driven oscillating saws.
The Mark I trench knife is an American trench knife designed by officers of the American Expeditionary Force (AEF) for use in World War I. It has a 6.75 in (17.1 cm) double-edged dagger blade useful for both thrusting and slashing strokes, unlike previous U.S. trench knives such as the M1917 and M1918. The handle is made of cast bronze and uses a conical steel nut to hold the blade in place. The Mark I's blade was blued with a black oxide finish, the bronze handle was chemically blackened, with cast spikes on the bow of each knuckle. The spikes were intended to prevent an opponent from grabbing the knife hand, as well as to provide a more concentrated striking surface when employed in hand-to-hand combat.
The state of medical knowledge at the time of the Civil War was extremely primitive. Doctors did not understand infection, and did little to prevent it. It was a time before antiseptics, and a time when there was no attempt to maintain sterility during surgery. No antibiotics were available, and minor wounds could easily become infected, and hence fatal. While the typical soldier was at risk of being hit by rifle or artillery fire, he faced an even greater risk of dying from disease.
Paul Berger was a French physician and surgeon who practised in Paris at the Hôpital Tenon and was Professor of Clinical Surgery and Pathology at the Faculté de médecine de Paris. He is noted for Berger's operation, a method of interscapulothoracic amputation, and for improvements in hernia/intestinal suturing.
John Weiss & Son were London-based surgical instrument makers during the 1700s and 1800s.
Ancient Roman surgical practices developed from Greek techniques. Roman surgeons and doctors usually learned through apprenticeships or studying. Ancient Roman doctors such as Galen and Celsus described Roman surgical techniques in their medical literature, such as De Medicina. These methods encompassed modern oral surgery, cosmetic surgery, sutures, ligatures, amputations, tonsillectomies, mastectomies, cataract surgeries, lithotomies, hernia repair, gynecology, neurosurgery, and others. Surgery was a rare practice, as it was dangerous and often had fatal results. To perform these procedures, they used tools such as specula, catheters, enemas, bone levers, osteotomes, phlebotomes, probes, curettes, bone drills, bone forceps, cupping vessels, knives, scalpels, scissors, and spathas.
