Abstract
A improved needle and method of forming the improved needle from an elongated cylindrical shank. The needle is formed by first cutting or grinding one end of the shank to create a first bevel surface disposed at an angle to the longitudinal axis of the needle. Thereafter as many as five additional bevel surfaces are formed or ground at the end of the shank with each bevel surface removing at least a portion of the peripheral edge of a previously formed bevel surface.
