    a substantially planar surgical blade secured at the front end of said handle, said blade having a direction of cut extending along the length of the handle;

    actuating means disposed in a position to be engaged by the fingers of a user when holding the scalpel in a position of normal use and mounted for movement generally perpendicular to the plane of said blade and the direction of cut thereof relative to said handle;

    a blade guard constructed to cover at least any sharp portions of said blade and mounted for movement between a blade-guarded position in which said blade is covered and a blade-exposed position in which said blade may be used for cutting; and
