Abstract
A safety surgical knife has a blade guard and a knife blade holder. The knife blade is covered when the guard is extended to protect it. When the blade is extended to its full operating position the guard is simultaneously retracted. When the blade is retracted the guard is simultaneously extended to return to its protective position. A shaped knife handle acts as an orientation guide and an anti-roll prop keeps the knife from rolling over when placed on a flat surface.
