Zusammenfassung:	An explosive laminated cutting tool which provides a self sharpening edge. The improved cutting tool s preferably comprised of two softer metals adhered to a hard central layer forming the cutting edge, with the central layer being made of such a material as tungsten carbide. The central laminate layer is preferably perforated to allow the outer layers to fuse through the perforations to adhere to one another, thus creating a strongly bonded laminated cutting structure which may be self sharpening. A method for manufacturing the cutting tool is also described. Another embodiment comprises a laminate wherein one of the layers has a plurality of recesses in the surface facing another layer. The recesses are filled with particles such as tungsten carbide or diamond. When the layers are explosively welded together, the particles are fused in the weld area.
