ABSTRACT:
An improved cutting tool has a blade removably secured to a movable body. The body is provided with an elongated slot extending into the body from its outer surface and arranged transversely of the direction of tool movement. This slot is bounded by spaced leading and trailing wall surfaces arranged to face one another and separated by an intermediate base surface. A blade is preferably arranged in the slot such that its leading surface is in area contact with the body leading wall surface. The trailing surface of the blade is provided with a plurality of serrations. A wedge, having a plurality of serrations on its leading surface, is insertable into the slot between the blade and the body trailing wall surface. The serrations on the blade and wedge mesh and interlock with one another, and permit the blade to be incrementally positioned relative to the wedge. A tongue extending outwardly from the wedge trailing surface is insertable into a cooperative groove recessed in the body trailing wall surface. The interlocked tongue and groove prevent the wedge from moving relative to the body in a direction transverse to the longitudinal axis of the tongue.
