Hand tools

File:A file (or hand-file) is a hand tool used to shape material by cutting. A file typically takes the form of a hardened steel bar, mostly covered with a series of sharp, parallel ridges or teeth.
Most files have a narrow, pointed tang at one end to which a handle can be fitted.
.


Screw: It is named a screw to a cylindrical mechanical component provided with head, generally metallic, though they can be of wood or plastic used in the fixation(fixing) of a few pieces with others, which is provided with a cane roscada with triangular coil, which by means of a force of twist exercised in his(her,your) head with a suitable key or with a screwdriver, can get in a hole roscado to his(her,your) measure or to cross the pieces and to mate to a nut.








Screwdriver:A screw has a head with a contour such that an appropriate screwdriver tip can be engaged in it in such a way that the application of sufficient torque to the screwdriver will cause the screw to rotate.








Pliers:Pliers are hand tools, designed primarily for gripping objects by using leverage. Pliers are designed for numerous purposes and sometimes require different jaw configurations to grip, turn, pull, or crimp a variety of things. They are a tool common to many dexterous trades and occupations. Many types of pliers also include jaws for cutting.










Hammer:A hammer is a tool meant to deliver an impact to an object. The most common uses are for driving nails, fitting parts, and breaking up objects. Hammers are often designed for a specific purpose, and vary widely in their shape and structure. Usual features are a handle and a head, with most of the weight in the head. The basic design is hand-operated, but there are also many mechanically operated models for heavier uses.






Saw:A saw is a tool that uses a hard blade or wire with an abrasive edge to cut through softer materials. The cutting edge of a saw is either a serrated blade or an abrasive. A saw may be worked by hand, or powered by steam, water, electric or other power.











Vise:A vise or vice (see under miscellaneous spelling differences) is a mechanical screw apparatus used for holding or clamping a work piece to allow work to be performed on it with tools such as saws, planes, drills, mills, screwdrivers, sandpaper, etc. Vises usually have one fixed jaw and another, parallel, jaw which is moved towards or away from the fixed jaw by the screw.











Adjustable wrench:An adjustable spanner, shifting spanner, shifter, crescent wrench or adjustable-angle head wrench (American English) is a tool which can be used to loosen or tighten a nut or bolt.











Clamp bar clamp:A clamp is a fastening device to hold or secure objects tightly together to prevent movement or separation through the application of inward pressure. In the United Kingdom and Australia, the term cramp is often used instead when the tool is for temporary use for positioning components during construction and woodworking; thus a G cramp or a sash cramp but a wheel clamp or a surgical clamp.










Scissors:The scissors are a tool of court(cut) used in wide areas of the human activity. It(he,she) consists of two metallic leaves(sheets) sharpened by the interior side, ended in a hollow where they can introduce the fingers, and articulated in an axis(axle) for his(her,your) ends.










Tape rule:. The tape rule used in measurement of distances is constructed in a thin sheet of steel to the chrome, or of aluminium, or of the planned one of carbon fibers joined by means of a polymer of teflon.













Punch:A punch is a hand or mechanical tool designed to pierce an object or material, or for stamping a design on a malleable surface that will hold the impression, such as wood, leather, metal or paper.














Chisel:A chisel is a tool with a characteristically shaped cutting edge (such that wood chisels have lent part of their name to a particular grind) of blade on its end, for carving and/or cutting a hard material such as wood, stone, or metal.











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 create a wooden object.












Drill: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 create a wooden object.

















Nail:A thin and sharp-pointed bar, which is inserted in tables, walls and partitions by a hammer.
















Mallet:Mallet is a hand tool that serves to throb or percutir; it(he,she) has the form of a hammer but it(he,she) is of major size and weight.










Rule:A rule is a instrument of measurement.










Sandpaper:The sandpaper is used to remove small fragments of material of the surfaces to leave his(her,your) smooth faces, since(as,like) in case of detailed of wood, like preparation to do(paint) or to varnish.















Gag:A gag is a tool that by means of a mechanism of screw or of another type allows to exercise and to support a force of compression on a piece to hold her for friction.
