Example ways of forming double-bladed scalpels and constituent parts are described. In one aspect a sleeve for coupling two-conventional scalpels together to form a double-bladed scalpel is described. Also described are male and female fastening mechanisms disposed along the sides of two independent scalpels. Each scalpel may be used independently of the other, or mated together via the fasteners to form a single double-bladed scalpel. In another aspect, a bracket is used to form a double-bladed scalpel from two-conventional scalpels. In another example, a double-bladed scalpel with a single handle is described.
