A heavy-duty, hand-held, surgical instrument used to remove pieces of bone or other hard tissue during orthopaedic and plastic surgery procedures. It typically comprises a handle proximally which becomes a shaft that terminates in a convex profile with a sharp, semi-lunar, bevelled cutting edge to facilitate tissue removal. It is hand-held by the surgeon who will use a surgical mallet or hammer to manually impart an impacting force to the proximal end of the instrument. It is typically made of high-grade stainless steel and can be designed as a one-piece instrument (all steel) or the handle may be made of synthetic material (e.g., Tufnol). This is a reusable device.
