Abstract
A process for progressively manufacturing cutting edge needles or wire members. Needle blanks or wire blanks are cut from a roll of wire and mounted to a carrier strip. The carrier strip and needles are moved through a succession of coining dies and at least one trimming die, wherein the first coining die is an open coining die and the one or more successive coining dies are closed coining dies. The needle blanks or wire members are optionally curved, heat treated and electrochemically treated resulting in cutting edge needles or wire members formed without a grinding step and without adversely affecting point ductility.
