Grind
A blade's grind is its cross-sectional shape in a plane normal to the edge. Grind differs from Blade#Knife blade profiles .28Patterns.29, 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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Straight Razor
A straight razor is a razor with a blade that can fold into its handle. They are also called open razors and cut-throat razors. The predecessors of the modern straight razors include bronze razors, with cutting edges and fixed handles, produced by craftsmen from Ancient Egypt during the New Kingdom (1569 — 1081 BC). Solid gold and copper razors were also found in Ancient Egyptian tombs dating back to the 4th millennium BC. The first steel-edged cutthroat razors were manufactured in Sheffield in 1680. By the late 1680s, early 1690s, razors with silver-covered handles along with other Sheffield-made products known as "Sheffield wares" were being exported to ports in the Gulf of Finland, approximately 1200 miles (1931 km) from Sheffield. From there, these goods were probably sent to Finland and even Russia. By 1740, Benjamin Huntsman was making straight razors complete with decorated handles and hollow-ground blades made from cast steel, using a process he invented. Huntsma ...

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 and a smaller serrated blade utility knife — there are also many specialized knives that are designed for specific tasks such as a toughness, tough cleaver, a small #Paring, paring knife, and a bread knife. Kitchen knives can be made from several different materials, though the most common is a hardened steel blade with a wooden handle. Historically, knives were made in "knife cities" that are noted for being the best at their production in that country with the pre-emininent, in Europe, being: Sheffield in Yorkshire, North of England; Thiers, Puy-de-Dôme in the Auvergne of France; Solingen in the North Rhine-Westphalia, Northern Rhineland of Germany; and Eskilstuna of Södermanland County in Sweden. Each of these produced knives in a styles particular to the city, with Thiers especially bei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honing (metalworking)
Honing is an abrasive machining process that produces a surface integrity, precision surface on a metal workpiece by scrubbing an abrasive grinding stone or grinding wheel against it along a controlled path. Honing is primarily used to improve the geometric form of a surface, but can also improve the surface finish. Typical applications are the finishing of cylinder (engine), cylinders for internal combustion engines, air bearing spindle (tool), spindles and gears. There are many types of hones, but all consist of one or more abrasive stones that are held under pressure against the surface they are working on. Other similar processes are lapping and superfinishing. Honing machines A honing machine is a precision tool used in machining to improve the surface finish and dimensional accuracy of component. It operates by using abrasive honing tools, which rotate and reciprocate inside the components, typically a cylinder or bore. This process enhances the internal surface quality ...

Blade Geometry
The term ''blade geometry'' refers to the physical properties of a sword blade: cross-section (or grind) and taper. Blade geometry Blade geometry is a crucial aspect of knife and sword design, influencing both the performance and usability of cutting tools. Cross-section The cross-section of a blade is the primary way of determining its function and place in history. Early Middle Ages Early Viking and medieval European blades tended to have a lenticular cross-section. This type of design lacks a strong central ridge in the middle of the blade. The flexibility these blades have illustrates the purpose that they served, as primarily cutting weapons, that could also be used with the thrust. Late Middle Ages With the improvement in the defensive capabilities of armor in the High and Late Middle Ages, the cross-section of the sword blade adapted to suit the needs of warriors. Swords began to favour rigidity over flexibility as more rigid blades allowed for the stronger thrusts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polishing
Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations). In some materials (such as metals, glasses, black or transparent stones), polishing is also able to reduce diffuse reflection to minimal values. When an unpolished surface is magnified thousands of times, it usually looks like a succession of mountains and valleys. By repeated abrasion, those "mountains" are worn down until they are flat or just small "hills". The process of polishing with abrasives starts with a coarse grain size and gradually proceeds to the finer ones to efficiently flatten the surface imperfections and to obtain optimal results. Mechanical properties The strength of polished products can be higher than their unpolished counterparts owing to the removal of stress concentrations pres ...

While much of this work can be accomplished with a few general-purpose knives — notably a large chef's knife and a smaller serrated blade utility knife — there .... A knife most simply has either a rectangular or wedge-shaped cross-section ( sabre-grind v. flat-grind, but may also have concave indentations or hollows, whose purpose is to reduce adhesion of the food to the blade, so producing a cleaner and easier cut. This is widely found in Japanese knives, and in the West is particularly found in meat carving knives, though also in knives for soft cheese, and some use for vegetables. These indentations take several forms: * Granton knives have gently rounded flutings ground into the edge that alternate on either side of the knife and extend from the edge to the middle of the blade. This design was developed and patented in 192 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Japanese Cutlery
A Japanese kitchen knife is a type of kitchen knife used for food preparation. These knives come in many different varieties and are often made using traditional Japanese blacksmithing techniques. They can be made from stainless steel, or ''hagane'', which is the same kind of steel used to make Japanese swords. Most knives are referred to as or the variation ''-bōchō'' in compound words (because of rendaku) but can have other names including . There are four general categories used to distinguish the Japanese knife designs: handle (Western vs. Japanese); blade grind (single bevel, '' kataba'' v. double bevel, '' ryōba''); steel (stainless v. carbon); and construction (laminated v. mono-steel). Handles Western handles have a bolster and a full or partial tang. These handles are often heavier, but are smaller in volume and surface area than most Japanese handles. The scale materials are often synthetic or resin-cured wood and are non-porous. Chefs who prefer the feel of a W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Razor Strop
A razor strop or simply a strop (sometimes called a razor strap or strap) is a flexible strip of leather, canvas, denim fabric, balsa wood, or other soft material, used to straighten and polish the blade of a straight razor, a knife, or a woodworking tool such as a chisel. In many cases stropping re-aligns parts of the blade edge that have been bent out of alignment. In other cases, especially when an abrasive polishing compound is used, stropping may remove a small amount of metal (functionally equivalent to lapping). Stropping can also burnish (i.e., push metal around on) the blade. The strop may be a hanging strop or a hand-held paddle. Various abrasive compounds may be applied to the strop to aid in polishing the blade while stropping to obtain a mirror-like finish. Common abrasive compounds include half-micron diamonds, green chromium(III) oxide, white rouge (aluminum oxide), and jeweller's rouge (iron(III) oxide). Use Stropping is traditionally associated with straig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kris
The kris or is a Javanese culture, Javanese asymmetrical dagger with a distinctive blade-patterning achieved through alternating laminations of iron and nickelous iron (''pamor''). The kris is famous for its distinctive wavy blade, although many have straight blades as well, and is one of the Weapons of silat, weapons commonly used in the ''pencak silat'' martial art native to Indonesia. Kris have been produced in many regions of Indonesia for centuries, but nowhere—although the island of Bali comes close—is the kris so embedded in a mutually-connected whole of ritual prescriptions and acts, ceremonies, mythical backgrounds and epic poetry as in Central Java. Within Indonesia the kris is commonly associated with Javanese culture, although other ethnicities in it and surrounding regions are familiar with the weapon as part of their cultures, such as the Balinese people, Balinese, Sundanese people, Sundanese, Malays (ethnic group), Malay, Madurese people, Madurese, Banjar peop ...

Deba Bōchō
— "fish-preparer" — are a style of Japanese kitchen knives primarily used to cut fish, though are also used occasionally in cutting meat. ''Debas'' have wide blades and are the thickest of all Japanese kitchen knives and come in different sizes — sometimes up to in length and thick — but usually considerably shorter, normally between long with a blade between thick. The larger form of knife is called an ''hon-deba'', ("true deba") whereas the smaller form is a ''ko-deba''. The ''deba bōchō'' first appeared during the Edo period in Sakai. Following the traditions of Japanese knives, they have just a single bevel to the edge — with an urasuki hollow back on premium blades — so generally come in just right-handed versions, but left-handed ones can be found in specialist shops. It is designed to behead and fillet fish. A deba's thickness, and often a more obtuse angle on the back of the heel allow it to cut off the heads of fish without damage. The rest of the ...
