Surgical Blades & Scalpels
A scalpel, or lancet, or bistoury, is a small and extremely sharp bladed instrument used for surgery, anatomical dissection and podiatry.
Scalpel blades are usually made of hardened and tempered steel, stainless steel, or high carbon steel; Charles Russell Bard and Morgan Parker, founders of the Bard-Parker Company. Morgan Parker patented the 2-piece scalpel design in 1915 and Bard-Parker developed a method of cold sterilization that would not dull the blades, as did the heat-based method that was previously used.
-> The world's first scalpel blade patent
