An ergonomically balanced safety scalpel that includes a pair of matched handle halves slidingly cooperative into a closed position and an open position. When in use, the handle halves are slidingly positioned in the closed position to expose the blade. The handle halves are slidingly repositioned relative to each other into the open position, when the safety scalpel is not in use, to extend one handle half relative to the other handle half whereby the blade is shielded therebetween.
