The process includes steps of forming a flat blank in unitary attachment with a carrier strip and coining edges of the tip of each flat blank, arcuately shaping the blank, and closeably forming the arcuate blank to create a medical needle having a holding portion, a cannulated portion and a tip. In addition, the cannulated portion may be encased for fluid delivery or grooved so the needle may be split.
