Which orthopedic instrument is bevelled on one side and shaves bones?

• A. Chisel
• B. Gouge
• C. Rasp
• D. Osteotome

Answer: (A)

Bevelled on one side signifies a straight surgical blade ground for a paring, shaving action. This single-beveled edge lets you advance along the bone surface and remove thin layers to shape or smooth it without gouging or tearing. That precise shaving is what makes a chisel the best fit for this task in orthopedic work: you can pare away bone to achieve the desired contour with controlled, shallow cuts using a mallet or hand pressure.

The other tools have different purposes: a curved-edge gouge is meant for scooping and shaping recesses, not for flat-surface shaving; a rasp is a rough file for finishing with teeth rather than a smooth paring cut; and an osteotome is intended to cut or split bone rather than shave it to a smooth plane.
