Abstract
A sheet metal file includes a main body composed of a sheet metal member that is flexible, and cutting edges raised by setting on a surface, on a first side, of the main body. The sheet metal file is allowed to smooth an object to be smoothed. The main body is an elastic member. The cutting edges are formed so that a driving depth with respect to the main body is in a range of 20 to 40% of a thickness of the main body. The sheet metal file is allowed to smooth an object to be smoothed with the surface of the main body on which the cutting edges are raised facing a curved surface of the object to be smoothed and with the main body bent along the curved surface.
