Skeleton Knife
A skeleton knife refers to two different types of knives, a kitchen knife and an unadorned penknife. Cheese knife The first type of skeleton knife is a small kitchen knife that typically has three large holes on its blade used for cutting fruit or cheese. The purpose of these holes is to reduce the surface area of the blade so that sticky foods do not cling to it. Most skeleton knives are used for cutting very soft foods. The knife was created by a Swiss restaurant and after its creation and advertisement it was stolen by many cutlery companies and private manufacturers, and is now widely manufactured by companies like Victorinox. Penknife The less commonly known type of skeleton knife is a penknife that was made without bolsters or handle material and sold to jewelers or other artisans for final finishing. These types of knives were mostly made in the 19th century and as late as 1950. Wostenholm of Sheffield, England Sheffield is a city in South Yorkshire, England, wh ...

Penknife
Penknife, or pen knife, is a British English term for a small folding knife. Today the word ''penknife'' is the common British English term for both a pocketknife, which can have single or multiple blades, and for multi-tools, with additional tools incorporated into the design. Originally, penknives were used for thinning and pointing quills (cf. ''penna'', Latin for ''feather'') to prepare them for use as dip pens and, later, for repairing or re-pointing the nib. A penknife might also be used to sharpen a pencil, prior to the invention of the pencil sharpener. In the mid-1800s, penknives were necessary to slice the uncut edges of newspapers and books. A penknife did not necessarily have a folding blade, but might resemble a scalpel or chisel by having a short, fixed blade at the end of a long handle. One popular (but incorrect) folk etymology makes an association between the size of a penknife and that of a small ballpoint pen. During the 20th century there has been a prolifer ...

Kitchen Knife
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] |
Surface Area
The surface area of a solid object is a measure of the total area that the surface of the object occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with flat polygonal faces), for which the surface area is the sum of the areas of its faces. Smooth surfaces, such as a sphere, are assigned surface area using their representation as parametric surfaces. This definition of surface area is based on methods of infinitesimal calculus and involves partial derivatives and double integration. A general definition of surface area was sought by Henri Lebesgue and Hermann Minkowski at the turn of the twentieth century. Their work led to the development of geometric measure theory, which studies various notions of surface area for irregular objects of any dimension. An important example is the Minkowski cont ...

Blade
A blade is the portion of a tool, weapon, or machine with an edge that is designed to puncture, chop, slice or scrape surfaces or materials. Blades are typically made from materials that are harder than those they are to be used on. Historically, humans have made blades from flaking stones such as flint or obsidian, and from various metal such as copper, bronze and iron. Modern blades are often made of steel or ceramic. Blades are one of humanity's oldest tools, and continue to be used for combat, food preparation, and other purposes. Blades work by concentrating force on the cutting edge. Certain blades, such as those used on bread knives or saws, are serrated, further concentrating force on the point of each tooth. Uses During food preparation, knives are mainly used for slicing, chopping, and piercing. In combat, a blade may be used to slash or puncture, and may also be thrown or otherwise propelled. The function is to sever a nerve, muscle or tendon fibers, or bloo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knife
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, a ...

Cutlery
Cutlery (also referred to as silverware, flatware, or tableware), includes any hand implement used in preparing, serving, and especially eating food in Western culture. A person who makes or sells cutlery is called a cutler. The city of Sheffield in England has been famous for the production of cutlery since the 17th century and a train – the ''Master Cutler'' – running from Sheffield to London was named after the industry. Bringing affordable cutlery to the masses, stainless steel was developed in Sheffield in the early 20th century. The major items of cutlery in Western culture are the knife, fork and spoon. These three implements first appeared together on tables in Britain in the Georgian era. In recent times, hybrid versions of cutlery have been made combining the functionality of different eating implements, including the spork (''sp''oon / f''ork''), spife (''sp''oon / kn''ife''), and knork (''kn''ife / f''ork''). The sporf or splade combines all three. Etymology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victorinox
Victorinox () is a knife manufacturer and watchmaker based in the town of Ibach, in the Canton of Schwyz, Switzerland. It is well known for its Swiss Army knives. The Swiss Army knives made by Victorinox are made of a proprietary blend steel from Germany and France. Since its acquisition of rival Wenger in 2005, it has become the sole supplier of multi-purpose knives to the Swiss army. It is the biggest manufacturer of pocket knives in the world; in addition, the company licenses its logo for watches, apparel, and travel gear. History Founding The company was founded in 1884 as ''Messerfabrik Carl Elsener'', the workshop of Karl Elsener in Ibach. Elsener, in 1891 co-founded ''Schweizerischer Messerschmiedverband'', an association of Swiss knife manufacturers. Elsener and his colleagues from this time delivered knives to the Swiss army. In 1892, most of Elsener's colleagues left the enterprise, as it became apparent that Solingen manufacturers could deliver at a lower p ...

Sheffield, England
Sheffield is a city in South Yorkshire, England, whose name derives from the River Sheaf which runs through it. The city serves as the administrative centre of the City of Sheffield. It is historically part of the West Riding of Yorkshire and some of its southern suburbs were transferred from Derbyshire to the city council. It is the largest settlement in South Yorkshire. The city is in the eastern foothills of the Pennines and the valleys of the River Don with its four tributaries: the Loxley, the Porter Brook, the Rivelin and the Sheaf.
