Nail file

Nail files are among the principal components of the various sets of cosmetic equipment. Finger nail files are generally purely utilitarian devices intended for abrading finger nails. They generally comprise planar members having a rough surface suitable for abrading finger nails. Finger nail files are generally fabricated in one of two ways. The file may be formed from a stratum of metal, such as steel, which is scored or otherwise treated to have a roughened or abrasive surface. There are currently two principle types of nail files or polishers in popular use. There are solid metal (usually steel) files with integral filing surfaces, usually formed by stamping or grinding an abrasive surface onto one or both surfaces of a steel sheet or strip. These files are quite durable, but they are also relatively expensive, especially when a very fine grade of file is required. The second kind of file currently available is manufactured from cardboard or very thin wood, which is provided with an emery finish. As can be expected, such a product is fairly inexpensive, but not very durable.
