Surgical Scissor Blade Definition

Most surgical scissors are produced with various blade definitions, depending on the surgical specialty and the material being cut.

The three primary blade definitions are:

  1. Stainless Blades: Scissors with stainless blades are the most common. The entire scissor is made out of the same metal (stainless steel) and there are no distinctly indentifiable colored rings.
  2. Tungsten Carbide Blades: Inserted only along the cutting edge surface of the blade is the mtal, Tungsten Carbide. These Tungsten Carbide strips are much harder than stainless steel. Once sharpened, these Tungsten Carbide blades stay sharper longer and are attached to the stainless steel scissor via welding or vacuum brazing. These Tungsten Carbide “strips” cannot be replaced once life-worn. Tungsten Carbide scissors have gold rings to distinguish this design.
  3. Black-Handled: These scissors are known as Microgrind or Super Cut scissor in the industry. The unique feature of these scissors is the sharpening technique employed on one of the blades. This scissor has a blade that will lance/slice through tissue with its knife-edge blade. All other scissors crush, resulting in cutting, whereas the black-handled scissor slices tissue. Black-handled scissors require special sharpening techniques and must be resharpened three to four times per year. The identifying feature of these scissors is the black colored rings.
