ABSTRACT:
In the production of a suture needle, a distal end portion of an elongated material is ground into a generally quadrangular pyramid shape. Then, the distal end portion of the elongated material is further ground into a generally triangular-pyramid shape, so that the distal or foremost end of the elongated material is positively pointed. The suture needle has four main surfaces and an auxiliary surface. The above triangular-pyramid shape is defined by two of the main surfaces and the auxiliary surface.
