Abstract: A manicure file has a generally rectilinear shape and is made of sheet stock and has a holding section sized to be graspable between a thumb and finger, a first flange is formed up, a second flange is formed down, there is abrading medium on the flanges, and the file presents many different angles and configurations of abrading surface and is particularly well suited for preventing ingrown nails and nail damage. An alternative file is normally flat and has a flexural line extending across the file, the file will fold under pressure to present the abrading surfaces. A method of making these files has the steps of forming the flanges off of the holding sections, and constructing abrading medium on the flanges.
