Why Disposafe?

Surgical Blades & Scalpels

A scalpel, or lancet, or bistoury, is a small and extremely sharp bladed instrument used for surgery, anatomical dissection and podiatry.

Some History

Scalpel blades are usually made of hardened and tempered steelstainless 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

What makes a good surgical blade?

  • Right raw material with correct alloy mixture

  • Deep understanding of Heat treatment

process and temperature control

  • Correct Grinding Process

      1. High Quality Grinding Wheel

      2. Superior Primary Grind angle 

      3. Correct width of cut

      4. Correct Cleaning Process

  • Superior Packaging

  • Correct Hardness for CS is >800 HV 

  • Correct Hardness for SS is >700 HV
