ABSTRACT:
An improved tool, such as a scissors, shears and the like, and an improved method of making such a tool is disclosed. The improved tool comprises two cooperating members that are interconnected so as to be pivotally movable, with respect to each other and about a connection point, between an open position and a closed position. The members each have a handle at their one end, a shank portion disposed between its handle and the connection point, and a blade portion disposed between the connection point and their other end. Each of the shank portions of the members have an inside face and an outside face, and each of the blade portions of the members have an inside face, an outside face and a cutting edge extending from adjacent to the connection point and to the other end of the member.
During the practice of the improved method, the outside face of the shank portion of one of the members is punched so that a bearing dimple is formed on the inside face of this shank portion. The bearing dimple projects from and above the surface of the inside face of the shank portion of the one member so that the bearing dimple may contact the inside face of the shank portion of the other member as the first and second members are moved toward their closed position and so that there is point contact between the cutting edges of the members as the members are moved toward their closed position.
