File (tool)

A file is a metalworking, woodworking and plastic working tool used to cut fine amounts of material from a work piece. It most commonly refers to the hand tool style, which takes the form of a steel bar with a case hardened surface and a series of sharp, parallel teeth. Most files have a narrow, pointed tang at one end to which a handle can be fitted.

A similar tool is the rasp. This is an older form, with simpler teeth. As they have larger clearance between teeth, these are usually used on softer, non-metallic materials.

Related tools have been developed with abrasive surfaces, such as diamond abrasives or silicon carbide. Because of their similar form and function, these have also been termed 'files'.

History

Early filing or rasping (the distinction is emic, not etic) 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 stone (for example, sandstone). Relatedly, lapping is also quite ancient, with wood and beach sand offering a natural pair of lap and lapping compound. The Disston authors state, "To abrade, or file, ancient man used sand, grit, coral, bone, fish skin, and gritty woods,—also stone of varying hardness in connection with sand and water."

201 file

A 201 file is set of documents maintained by the US government for members of the United States armed forces. 201 files usually contain documents describing the member's military and civilian education history. A 201 file may also contain personal information such as home of record, and awards documents. Typically, a 201 file contains one or more of the following:

The 201 file is an important document for service members to maintain, as the documents it contains are important for access to benefits such as the VA Loan and the GI Bill.

Copies of the 201 file can also be requested from the National Archives by service members and their families.

The Central Intelligence Agency also uses the term "201 File" to refer to their own personnel records used for analogous purposes.
