Shave biopsy instrument: An ergonomic modification of razor blade

Abstract

The razor blade has been used by dermatologists as an alternative tool for performing shave excision and biopsy owing to its superior sharpness and flexibility. It is inexpensive and freely available but the bare blade design carries the risk of accidental injury to the operator and patient. We describe an easy modification of the razor blade for better grip, control, and safety in obtaining cutaneous shave specimens.
