Disposable blades for a clean cut every time

  • 100 per box
  • Stainless steel
  • Individually wrapped and sterile


Surgical blades are made of hardened and tempered steel or carbon steel. This kind of material is crucial in order to achieve a the high degree of sharpness required for a perfect first tissue incision. Other choices for surgical blades include titanium, ceramic, diamond and obsidian.

When you choose the blades for your application, consider the following:

  • What kind of procedure you are doing?
  • What  material you will be cutting?
  • What shape of blade is required?
  • Will you need a single use or a reusable blade?
  • Will the spine of the blade (unsharpened edge) affect your application?
  • What shape of the slot in the blade (for replaceable blades) do you need for your handle?
  • Should the edge of the blade be open edge (surgically ground on both sides but finished on just one side) or closed edge (finished on and sharpened on both sides)?

Why are all surgical blades numbered?

Charles Russell Brand and Morgan Parker invented the 2 two piece (blade-handle) scalpel, and they assigned numbers 10-20 to blades and the numbers 1-9 to the handles. With small variations, their numbering system is still in place today. The number of the blade indicates the blade size and shape. Surgical blade handles are also known as BP handles after Brand & Parker.
