A utility knife is any type of knife used for general manual work purposes. Such knives were originally fixed-blade knives with durable cutting edges suitable for rough work such as cutting cordage, cutting/scraping hides, butchering animals, cleaning fish scales, reshaping timber, and other tasks. Craft knives are small utility knives used as precision-oriented tools for finer, more delicate tasks such as carving and papercutting.
A knife 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 Originally made of wood, bone, and stone, over the centuries, in step with improvements in both metallurgy and manufacturing, knife blades have been made from copper, bronze,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.
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".
The Swiss Army knife is a multi-tool pocketknife manufactured by Victorinox. The term "Swiss Army knife" was coined by American soldiers after World War II after they had trouble pronouncing the German word "Offiziersmesser", meaning "officer’s knife".
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.
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.
Dremel is a multinational brand of power tools, focusing on home improvement and hobby applications. Dremel is known primarily for its rotary tools such as the Dremel 3000, 4000 and 8200 series which are similar to the pneumatic die grinders used in the metalworking industry by tool or moldmakers. Dremel later expanded its product range and now produces butane tools, benchtop and hand-held saws and oscillating tools.
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.
Wüsthof is a knife-maker based in Solingen, Germany. Family owned for seven generations, the company's main products are mid-priced to high-end kitchen knives for domestic and professional use. Wüsthof is one of the leading manufacturers of chef's knives.
A serrated blade is one with a toothlike rather than a plain edge, and is used on saws and on some knives and scissors. It is also known as a dentated, sawtooth, or toothed blade. Most such blades are scalloped, having edges cut with curved notches, common on wood saws and bread knives.
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 butcher knife or butcher's knife is a knife designed and used primarily for the butchering or dressing of animal carcasses.
A ceramic knife is a knife with a ceramic blade typically made from zirconium dioxide (ZrO2; also known as zirconia), rather than the steel used for most knives. Ceramic knife blades are usually produced through the dry-pressing and firing of powdered zirconia using solid-state sintering. The blades typically score 8.5 on the Mohs scale of mineral hardness, compared to 4.5 for normal steel and 7.5 to 8 for hardened steel and 10 for diamond. The resultant blade has a hard edge that stays sharp for much longer than conventional steel blades. However, the blade is brittle, subject to chipping, and will break rather than flex if twisted. The ceramic blade is sharpened by grinding the edges with a diamond-dust-coated grinding wheel.
Knife making is the process of manufacturing a knife by any one or a combination of processes: stock removal, forging to shape, welded lamination or investment cast. Typical metals used come from the carbon steel, tool, or stainless steel families. Primitive knives have been made from bronze, copper, brass, iron, obsidian, and flint.
GLOBAL is a Japanese brand of kitchen knives and accessory tools owned and manufactured by the Yoshikin factory of Japan. The Yoshikin Factory is owned by the Watanabe family and located in Tsubame, Japan.
Elmer's Products, Inc. or simply Elmer's is an American-based company that has a line of adhesive, craft, home repair, and office supply products. It is best known as the manufacturer of Elmer's Glue-All, a popular PVA-based synthetic glue, in addition to other brands including Krazy Glue, ProBond and CraftBond adhesives, and X-Acto cutting tools.
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.
The history of school and office products brand Westcott dates back to 1872, when Henry Westcott, together with his two sons Charles and Frank Westcott, started manufacturing wooden furniture used by printers and trellis units in Seneca Falls, New York. The company expanded rapidly and became one of the largest manufacturers of desk and school rulers in the world. Throughout its history it remained in Westcott family hands until it was purchased by Acme Shear Co. in 1968, which later changed its name to Acme United Corporation.
The splitting band knife is a kind of knife used in several fields including: tannery, EVA/rubber, foam, cork, shoe and leather goods, paper, carpet and other soft sheet materials. It is a power tool which is very similar in operation to a band saw, with an endless loop blade; the material to be cut is supported by a flat table.
