A screw type shaving cutter and a method of producing the same. A large number of cutting edges are formed on the flanks of the thread of the cutter. Each cutting edge is inclined along a curve or a straight line in the trailing direction as viewed in the direction of rotation of the cutter in use. This shaving cutter is produced by forming a screw body by cutting a metal blank into a form of a screw, and forming a number of cutting edges on the flanks of the thread of the screw body by reciprocatingly moving a cutting tool on the flanks of the thread, while rotating the screw body continuously in one direction.
