How to test scissors for sharpness

CRCST practice question · Preparation & Packaging

A technician is testing the sharpness of a pair of Metzenbaum scissors. How should the test be done?

  • A. Cut a folded 4x4 gauze sponge and see whether threads pull
  • B. Cut a strip of indicator tape and see whether the edges fray
  • C. Run a fingertip along the blade edge to feel for nicks
  • D. Cut the manufacturer-recommended test material and check that it cuts cleanly to the tips without catching

Answer

D. Cut the manufacturer-recommended test material and check that it cuts cleanly to the tips without catching

Use the test material the manufacturer recommends: the scissors should cut cleanly all the way to the tips without snagging or folding the material. Gauze and tape don't give a consistent standard, and testing a blade with your finger is unsafe.
