Cast/plaster knife

A cast knife is a flat-bladed, hand-held surgical instrument designed specifically for cutting or trimming hardened plaster during cast removal or adjustment procedures. It features a short, robust cutting blade with a sharp edge, typically constructed from a single piece of high-grade stainless steel for durability and corrosion resistance. Clinically, it is used by orthopedic specialists and emergency personnel to safely and efficiently cut through plaster casts without injuring the underlying skin or tissue.

This device is classified as a reusable surgical instrument, intended for repeated use after appropriate sterilization between patients. It is typically supplied by medical device distributors and is subject to standard regulatory controls for reusable surgical tools, including material biocompatibility and sterility maintenance requirements. The category focuses exclusively on manual, non-powered instruments, excluding electric or battery-operated cast saws.
