ABSTRACT:
A double-bladed scalpel for cutting tissue sections from a tissue specimen for microscopic examination and the like. In a preferred embodiment the double-bladed scalpel is characterized by a pair of scalpel blades disposed in parallel, substantially coplanar relationship with respect to each other and connected to each other by a connecting element which may be folded such that the cutting margin of each scalpel blade is positioned in parallel, adjacent relationship with respect to the cutting margin of the opposite scalpel blade. One of the scalpel blades is provided with a handle slot for receiving a correspondingly-shaped blade mount protuberance formed on conventional scalpel handles to removably mount the double-bladed scalpel on the scalpel handle.
