Knife Sharpener
Knife sharpening is the process of making a knife or similar tool sharp by grinding against a hard, rough surface, typically a stone, or a flexible surface with hard particles, such as sandpaper. Additionally, a leather razor strop, or strop, is often used to straighten and polish an edge. Overview The smaller the angle between the blade and stone, the sharper the knife will be, but the less side force is needed to bend the edge over or chip it off. The angle between the blade and the stone is the ''edge angle'' – the angle from the ''vertical'' to one of the knife edges, and equals the angle at which the blade is held. The total angle from one side to the other is called the ''included angle'' – on a symmetric double-ground edge (a wedge shape), the angle from one edge to the other is thus ''twice'' the edge angle. Typical edge angles are about 20° (making the included angle 40° on a double-ground edge). The edge angle for very sharp knives can be as little as 10 degrees ...

The Knife Grinder By Massimiliano Soldani (c
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a ...

Scary Sharp
Scary sharp is a method of sharpening woodworking tools with sandpaper instead of conventional methods of Sharpening stone, oilstone or waterstone sharpening. The sandpaper referred to here can be any abrasive impregnated sheet used in the various industries to smooth surfaces and examples include glass paper, silicon carbide, emery cloth, etc. The sandpaper is affixed to another hard, flat substrate to create the sharpening surface. Sheet-glass is commonly used, but a machinist's granite surfacing block, marble baking slabs, plywood, medium-density fibreboard (MDF) or even jointer out-feed tables will produce satisfactory results. The method of fixation is usually a matter of the user's preference, and can include plain water (by means of surface tension), sprayed-on adhesive, or by simply using adhesive-backed abrasive paper. This is exactly the same method as that used by materials scientists in preparing polished samples for metallography. The basics of the method involves ...

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 versi ...

Bic Pen
The BIC Cristal (stylised as BiC Cristal and also known as the Bic pen) is an inexpensive, disposable ballpoint pen mass-produced and sold by Société Bic of Clichy, Hauts-de-Seine, France. It was introduced in December 1950 and is the best-selling pen in the world, with the 100 billionth sold in September 2006. It has become the archetypal ballpoint pen and is considered ubiquitous, to the extent that the Museum of Modern Art has made it a permanent part of its collection. Its hexagonal form and design mimics a standard pencil and it is sold in six types of point and 18 colours around the world. History In 1944, near the end of the Second World War, entrepreneur Marcel Bich bought a factory in Clichy, a suburb north of Paris, and with business partner Edouard Buffard founded ''Société PPA'' (later ''Société Bic'') in 1945. "PPA" stood for ''Porte-plume, Porte-mines et Accessoires'' – pens, mechanical pencils and accessories. During the war Bich had seen a ballpoint pe ...

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 ...

Mukimono
is the traditional Japanese art of decorative garnishing. Examples of this include carving traditional images (flowers, cranes, turtles and dragons) into skins of fruit and vegetables, as well as carving vegetables (such as daikon, carrot, eggplant) into attractive shapes such as flowers, twists, and fan shapes. These are commonly served as a garnish on the same plate as the meal, or on a small side plate. Carving is done using a kitchen knife. Mukimono is different from Thai fruit carving, which uses a sharp thin knife specifically designed for this purpose. Cutting food in Mukimono style is a way to create a sense of the four seasons. The taste of the four seasons improves the appearance of the cuisine and plays a major role in improving the flavor. See also * Vegetable carving * Fruit carving * Night of the Radishes The Night of the Radishes ( es, Noche de Rábanos, region=MX) is an annual event held on December 23 in Oaxaca City, Oaxaca, Mexico, dedicated to the car ...

Bending
In applied mechanics, bending (also known as flexure) characterizes the behavior of a slender structural element subjected to an external load applied perpendicularly to a longitudinal axis of the element. The structural element is assumed to be such that at least one of its dimensions is a small fraction, typically 1/10 or less, of the other two.Boresi, A. P. and Schmidt, R. J. and Sidebottom, O. M., 1993, Advanced mechanics of materials, John Wiley and Sons, New York. When the length is considerably longer than the width and the thickness, the element is called a beam. For example, a closet rod sagging under the weight of clothes on clothes hangers is an example of a beam experiencing bending. On the other hand, a shell is a structure of any geometric form where the length and the width are of the same order of magnitude but the thickness of the structure (known as the 'wall') is considerably smaller. A large diameter, but thin-walled, short tube supported at its ends an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buckling
In structural engineering, buckling is the sudden change in shape ( deformation) of a structural component under load, such as the bowing of a column under compression or the wrinkling of a plate under shear. If a structure is subjected to a gradually increasing load, when the load reaches a critical level, a member may suddenly change shape and the structure and component is said to have ''buckled''. Euler's critical load and Johnson's parabolic formula are used to determine the buckling stress in slender columns. Buckling may occur even though the stresses that develop in the structure are well below those needed to cause failure in the material of which the structure is composed. Further loading may cause significant and somewhat unpredictable deformations, possibly leading to complete loss of the member's load-carrying capacity. However, if the deformations that occur after buckling do not cause the complete collapse of that member, the member will continue to support ...

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 stee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
