A surgical instrument comprising a scalpel handle with a separate protective sheath for use in closed surgical procedures, such as arthroscopy. The protective sheath provides for atraumatic insertion of a scalpel blade into the body and to the actual operative site, minimizing the chance of accidental cutting of surrounding tissue. The handle portion is insertable into the tubular sheath from the distal tubular opening of the sheath. The sheath and handle combination may be engaged relative to each other in a plurality of functional positions.
