Abstract
A sterile surgical needle having a dark, non-reflective and non-flaking surface. The needle is produced by selecting an appropriately shaped needle having the desired degree of sharpness. The needle is treated to activate the surface and then immersed in a solution of sulfuric acid, potassium dichromate and water to form a dark, non-reflective, non-flaking surface. The needle is sterilized to produce a sterile surgical needle of improved visibility.
