Jointing (sharpening)
Jointing refers to the process of filing or grinding the teeth or knives of cutting tools prior to sharpening. The purpose of jointing is to ensure that all surfaces to be sharpened are of a consistent size and all imperfections have been removed. Jointing is usually the first step in the process of sharpening: *When sharpening a hand saw blade, the teeth are jointed by running a flat file over the tips of the teeth so that they are all of the same height. *Circular saw blades are jointed prior to sharpening so that all teeth protrude from the blade the same distance from the centre. *Jointer knives are ground until they are all the same length prior to sharpening. *The edges of a card scraper are jointed by running the edge over a file or a sharpening stone prior to using a burnisher A burnisher is a hand tool used in woodworking for creating a burr on a card scraper.

Sharpening
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. Tools and materials There are many ways of sharpening tools. Malleable metal surfaces such as bronze, iron and mild steel may be formed by beating or peening a flat surface into a sharp edge. This process also causes work hardening. An abrasive material may be rubbed against the cutting edge to be sharpened. The most traditional abrasive material is a natural stone such as sandstone or granite. Modern synthetic grinding wheels and flat sharpening stones can be manufactured in precise grades of abrasiveness according to the intended process. A sharp edge may be ' ...

Hand Saw
In woodworking and carpentry, hand saws, also known as "panel saws", are used to cut pieces of wood into different shapes. This is usually done in order to join the pieces together and carve a wooden object. They usually operate by having a series of sharp points of some substance that is harder than the wood being cut. The hand saw is a bit like a tenon saw, but with one flat, sharp edge. Handsaws have been around for thousands of years. Egyptian hieroglyphics exist depicting ancient woodworkers sawing boards into pieces. Ancient bow saws have been found in Japan. The cut patterns on ancient boards may be observed sometimes to bear the unique cutting marks left by saw blades, particularly if the wood was not 'smoothed up' by some method. As for preservation of handsaws, twenty-four saws from eighteenth-century England are known to survive.Olmert, Michael (1996).

File (tool)
A file is a tool used to remove fine amounts of material from a workpiece. It is common in woodworking, metalworking, and other similar trade and hobby tasks. Most are hand tools, made of a case hardened steel bar of rectangular, square, triangular, or round cross-section, with one or more surfaces cut with sharp, generally parallel teeth. A narrow, pointed tang is common at one end, to which a handle may be fitted.. A rasp is a form of file with distinct, individually cut teeth used for coarsely removing large amounts of material. Files have also been developed with abrasive surfaces, such as natural or synthetic diamond grains or silicon carbide, allowing removal of material that would dull or resist steel files, such as ceramic. History Early filing or rasping has prehistoric roots and grew naturally out of the blending of the twin inspirations of cutting with stone cutting tools (such as hand axes) and abrading using natural abrasives, such as well-suited types of st ...

Circular Saw
A circular saw is a power-saw using a toothed or abrasive disc or blade to cut different materials using a rotary motion spinning around an arbor. A hole saw and ring saw also use a rotary motion but are different from a circular saw. ''Circular saws'' may also be loosely used for the blade itself. Circular saws were invented in the late 18th century and were in common use in sawmills in the United States by the middle of the 19th century. A circular saw is a tool for cutting many materials such as wood, masonry, plastic, or metal and may be hand-held or mounted to a machine. In woodworking the term "circular saw" refers specifically to the hand-held type and the table saw and chop saw are other common forms of circular saws. "Skilsaw" and "Skil saw" have become generic trademarks for conventional hand-held circular saws. Circular saw blades are specially designed for each particular material they are intended to cut and in cutting wood are specifically designed for making ...

Jointer
A jointer or in some configurations, a jointer-planer (also known in the UK and Australia as a planer or surface planer, and sometimes also as a buzzer or flat top) is a woodworking machine used to produce a flat surface along a board's length. As a jointer, the machine operates on the narrow edge of boards, preparing them for use as butt joint or gluing into panels. A planer-jointer setup has the width that enables smoothing ''('surface planing')'' and leveling the faces (widths) of boards small enough to fit the tables. Name The jointer derives its name from its primary function of producing flat edges on boards prior to joining them edge-to-edge to produce wider boards. The use of this term probably arises from the name of a type of hand plane, the jointer plane, which is also used primarily for this purpose. "Planer" is the normal term in the UK and Australia for what is called a "jointer" in North America, where the former term refers exclusively to a thickness planer ...

Card Scraper
A card scraper or cabinet scraper is a woodworking shaping and finishing tool. It is used to manually remove small amounts of material and excels in tricky grain areas where hand planes would cause tear out. Card scrapers are most suitable for working with hardwoods, and can be used instead of sandpaper. Scraping produces a cleaner surface than sanding; it does not clog the pores of the wood with dust, and does not leave a fuzz of torn fibers. Types Card scrapers are available in a range of shapes and sizes, the most common being a rectangular shape approximately and with a thickness of . Another common configuration is the ''gooseneck'' scraper, which has a shape resembling a french curve and is useful for scraping curved surfaces. For scraping convex shapes such as violin fingerboards, small flexible rectangular scrapers are useful. Similarly, a card scraper can be used to manufacture complex mouldings by cutting the negative of the desired moulding into the steel, e.g. ...

Sharpening Stone
Sharpening stones, or whetstones, are used to sharpen the edges of steel tools such as knives through grinding and honing. Such stones come in a wide range of shapes, sizes, and material compositions. They may be flat, for working flat edges, or shaped for more complex edges, such as those associated with some wood carving or woodturning tools. They may be composed of natural quarried material or from man-made material. They come in various grades, which refer to the grit size of the abrasive particles in the stone. (Grit size is given as a number, which indicates the spatial density of the particles; a higher number denotes a higher density and therefore smaller particles, which give a finer finish to the surface of the sharpened object.) Stones intended for use on a workbench are called bench stones, while small, portable ones, whose size makes it hard to draw large blades uniformly over them, especially “in the field,” are called pocket stones. Often whetstones are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burnisher
A burnisher is a hand tool used in woodworking for creating a burr on a card scraper. Description Purpose-manufactured burnishers are polished smooth, typically made from high speed steel (HSS) or cemented carbide, and usually have wooden handles. The shaft profile is usually round, but other profiles include oval and triangular. Substitutes for shop-bought burnishers are often made with other common workshop items of hardened steels or cemented carbide, such as the back of a gouge, a bevel edged chisel, a nail punch, or an HSS drill bit. Alternatively the woodworker might use a carbide or HSS rod marketed for other uses. Limitations To work effectively, a burnisher must be much harder than the scraper. Modern scrapers are typically manufactured from harder steels than in the past, and require burnishing with harder materials, making some traditional makeshift burnishers less effective on modern scrapers.
