Surgical scissors

Surgical scissors are surgical instruments usually used for cutting. They include bandage scissors, dissecting scissors, iris scissors, operating scissors, stitch scissors, tenotomy scissors, Metzenbaum scissors, plastic surgery scissors, and Mayo scissors. Surgical scissors are usually made of very hard stainless steel for ongoing toughness. Some scissors have tungsten carbide reinforcements along their cutting edges. The hardness of this material allows the manufacturers to create sharper edges, which allows for easier and smoother cuts and keeps the scissors sharp for longer.
