⭐ Core Definition: Chisel

A chisel is a hand tool with a characteristic wedge-shaped cutting edge on the end of its blade. A chisel is useful for carving or cutting a hard material such as wood, stone, or metal.

Using a chisel involves forcing the blade into some material to cut it. The driving force may be applied by pushing by hand, or by using a mallet or hammer. In industrial use, a hydraulic ram or falling weight ('trip hammer') may be used to drive a chisel into the material.

Chisel in the context of Relief carving

In wood carving, relief carving is a type in which figures or patterns are carved in a flat panel of wood; the same term is also used for carving in stone, ivory carving and various other materials. The figures project only slightly from the background rather than standing freely. Depending on the degree of projection, reliefs may also be classified as high or medium relief.

Relief carving can be described as "carving pictures in wood". The process of relief carving involves removing wood from a flat wood panel in such a way that an object appears to rise out of the wood. Relief carving begins with a design idea, usually put to paper in the form of a master pattern which is then transferred to the wood surface. Most relief carving is done with hand tools, chisels and gouges, which often require a mallet to drive them through the wood.

Chisel in the context of Woodcut

Woodcut is a relief printing technique in printmaking. An artist carves an image into the surface of a block of wood—typically with gouges—leaving the printing parts level with the surface while removing the non-printing parts. Areas that the artist cuts away carry no ink, while characters or images at surface level carry the ink to produce the print. The block is cut along the wood grain (unlike wood engraving, where the block is cut in the end-grain). The surface is covered with ink by rolling over the surface with an ink-covered roller (brayer), leaving ink upon the flat surface but not in the non-printing areas.

Multiple colours can be printed by keying the paper to a frame around the woodblocks (using a different block for each colour). The art of carving the woodcut can be called xylography, but this is rarely used in English for images alone, although that term and xylographic are used in connection with block books, which are small books containing text and images in the same block. They became popular in Europe during the latter half of the 15th century. A single-sheet woodcut is a woodcut presented as a single stand alone image or print, as opposed to a book illustration.

Chisel in the context of Linocut

Linocut, also known as lino print, lino printing or linoleum art, is a printmaking technique, a variant of relief printing in which a sheet of linoleum (sometimes mounted on a wooden block) is used for a relief surface. A design is cut into the linoleum surface with a sharp knife, V-shaped chisel or gouge, with the raised (uncarved) areas representing a reversal (mirror image) of the parts to show printed. The linoleum sheet is inked with a roller (called a brayer), and then impressed onto paper or fabric. The actual printing can be done by hand or with a printing press.

Multi-color linocuts can be made by successively printing with a different block for each color as in a color woodcut, as the artists of the Grosvenor School frequently did. As Pablo Picasso demonstrated, such prints can also be achieved using a single piece of linoleum in what is called the "reductive" print method. Essentially, after each successive color is imprinted onto the paper, the artist then cleans the lino plate and cuts away what will not be imprinted for the subsequently applied color.

Chisel in the context of Hand tool

A hand tool is any tool that is powered by hand rather than a motor. Categories of hand tools include wrenches, pliers, cutters, files, striking tools, struck or hammered tools, screwdrivers, vises, clamps, snips, hacksaws, drills, and knives.

Outdoor tools such as garden forks, pruning shears, and rakes are additional forms of hand tools. Portable power tools are not hand tools.

Chisel in the context of Wood carving

Wood carving (or woodcarving) is a form of woodworking by means of a cutting tool (knife) in one hand or a chisel by two hands or with one hand on a chisel and one hand on a mallet, resulting in a wooden figure or figurine, or in the sculptural ornamentation of a wooden object. The phrase may also refer to the finished product, from individual sculptures to hand-worked mouldings composing part of a tracery.

The making of sculpture in wood has been extremely widely practised, but does not survive undamaged as well as the other main materials like stone and bronze, as it is vulnerable to decay, insect damage, and fire. Therefore, it forms an important hidden element in the art history of many cultures. Outdoor wood sculptures do not last long in most parts of the world, so it is still unknown how the totem pole tradition developed. Many of the most important sculptures of China and Japan, in particular, are in wood, and so are the great majority of African sculpture and that of Oceania and other regions. Wood is light and can take very fine detail so it is highly suitable for masks and other sculpture intended to be worn or carried. It is also much easier to work on than stone and can be carved more thinly and precisely due to its fibrous strength.

Chisel in the context of Jackhammer

A jackhammer (pneumatic drill or demolition hammer in British English) is a pneumatic or electro-mechanical tool that combines a hammer directly with a chisel. It was invented by William McReavy, who then sold the patent to Charles Brady King. Hand-held jackhammers are generally powered by compressed air, but some are also powered by electric motors. Larger jackhammers, such as rig-mounted hammers used on construction machinery, are usually hydraulically powered. These tools are typically used to break up rock, pavement, and concrete.

A jackhammer operates by driving an internal hammer up and down. The hammer is first driven down to strike the chisel and then back up to return the hammer to the original position to repeat the cycle. The effectiveness of the jackhammer is dependent on how much force is applied to the tool. It is generally used like a hammer to break the hard surface or rock in construction works and it is not considered under earth-moving equipment, along with its accessories (i.e., pusher leg, lubricator).

Chisel in the context of Draw knife

A drawknife (drawing knife, draw shave, shaving knife) is a traditional woodworking hand tool used to shape wood by removing shavings. It consists of a blade with a handle at each end. The blade is much longer (along the cutting edge) than it is deep (from cutting edge to back edge). It is pulled or "drawn" (hence the name) toward the user.

The drawknife in the illustration has a blade 23 cm (9.1 in) long, although much shorter drawknives are also made. The blade is sharpened to a chisel bevel. Traditionally, it is a rounded, smooth bevel. The handles can be below the level of the blade (as in the illustration) or at the same level.

Chisel in the context of 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, a block (placed on a table, or in ones hand), 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 diamonds, chromium(III) oxide, aluminum oxide, and iron(III) oxide.

Chisel in the context of Burin (lithic flake)

In archaeology and the field of lithic reduction, a burin /ˈbjuːrɪn/ (from the French burin, meaning "cold chisel" or modern engraving burin) is a type of stone tool, a handheld lithic flake with a chisel-like edge which prehistoric humans used for carving or finishing wood or bone tools or weapons, and sometimes for engraving images.

In archaeology, burin use is often associated with "burin spalls", which are a form of debitage created when toolmakers strike a small flake obliquely from the edge of the burin flake in order to form the graving edge.

Chisel in the context of Tang (tools)

A tang or shank is the back portion of the blade component of a tool or weapon where it extends into stock material or connects to a handle – as on a knife, sword, spear, arrowhead, chisel, file, coulter, pike, scythe, screwdriver, etc. One can classify various tang designs by their appearance, by the manner in which they attach to a handle, and by their length in relation to the handle.

Nakago is the term in Japanese, used especially when referring to the tang of the katana or the wakizashi.

Chisel in the context of Freestone (masonry)

A freestone is a type of stone used in masonry for molding, tracery and other replication work required to be worked with the chisel. Freestone, so named because it can be freely cut in any direction, must be fine-grained, uniform and soft enough to be cut easily without shattering or splitting. Some sources, including numerous nineteenth-century dictionaries, say that the stone has no grain, but this is incorrect. Oolitic stones are generally used, although in some countries soft sandstones are used; in some churches an indurated chalk called clunch is employed for internal lining and for carving.

Some have believed that the word "freemason" originally referred, from the 14th century, to a person capable of carving freestone.
