Abstract
A method for manufacturing a nail efficiently at low cost without a loss of material. The nail includes two legs bound together by a washer. One of the legs has a protrusion such that when the other leg is driven, it will spread by riding on the protrusion. In this method, a round rod stock is pressed except a portion thereof to form a head at one thereof, a trunk portion having a semicircular section with a flat surface between the head and the portion, and a tip portion at the other end of the rod stock. The portion forms the protrusion. The one of the legs is thus formed. The protrusion may be formed by pressing the rod from both sides.
