ABSTRACT:
The tool incorporates a plurality of penetrating blades arranged in a stamping plane. The blades are secured to a platform grid. The blades paralleling an edge of the platform form a closed end of the tool. The blades taper from the platform attached portion to a penetrating tip forming a tapering transverse profile. Blades terminating opposite the closed end of the tool include a mating blade face having a longitudinal profile complimentary to the transverse profile so that when the tool is positioned against other similar tools in making impressions, the closed end-to-open end interface is made without gaps or voids thereby eliminating hand work in the finishing operation.
