Abstract
A knife includes a blade reservoir and a sleeve slidable onto the knife to cover the reservoir. A latch prevents removing the sleeve unless depressed. The latch is located in a position requiring the knife to be turned into a position facing the blade reservoir upward before it can be actuated. In this manner, the blade reservoir must face upward when the sleeve is removed and accidental dropping of blades from the reservoir during opening is prevented.
