WHAT IS CLAIMED:

1. A heavy duty, configurable shear/crusher demolition tool, comprising:

(a) an upper jaw, a lower jaw, and a pivot group connecting the upper jaw and the lower jaw;

(b) a plurality of tooth holders mounted either on the upper jaw or the lower jaw;

(c) a plurality of teeth removably mounted to the plurality of tooth holders;

(d) a plurality of shear blade holders mounted either on the upper jaw or the lower jaw; and

(e) a plurality of shear blades removably mounted to the plurality of shear blade holders.

2. The demolition tool of claim 1, wherein the upper jaw further comprises an upper plate, the plurality of tooth holders and plurality of shear blade holders being mounted to the upper plate.

3. The demolition tool of claim 2, wherein the lower jaw further comprises a lower plate, the plurality of tooth holders and plurality of shear blade holders being mounted to the lower plate.

4. The demolition tool of claim 1, wherein the plurality of tooth holders further comprise a configurable number of tooth pockets receiving the teeth and fasteners mounting the teeth in the tooth pockets.

5. The demolition tool of claim 4, wherein the plurality of shear blade holders further comprise mounting surfaces receiving a configurable number of shear blades and fasteners mounting the shear blades to the mounting surfaces.

6. The demolition tool of claim 1, wherein the pivot group further comprises a pivot pin rotating with the upper jaw and a recessed end cap mounted to each end of the pivot pin.

7. The demolition tool of claim 6, wherein the pivot pin is press-fit into the upper jaw.

8. The demolition tool of claim 6, wherein the recessed end cap further comprises a tapered edge preventing damage to the pivot group.

9. The demolition tool of claim 6, further comprising at least one shim mountable in the upper jaw between the pivot pin and an end cap.

10. The demolition tool of claim 4, wherein each of the plurality of tooth pockets further comprises a flange with a flange aperture therethrough and wherein each of the plurality of teeth further comprises a leg with a leg aperture therethrough, the leg engaging the flange and the fastener engaging the flange aperture and the leg aperture to removably mount the tooth to the tooth pocket.

1 1. The demolition tool of claim 10, wherein the fastener is a bolt having a head with a flat surface and wherein the leg further comprises a flat surface engaging the flat surface of the head thereby preventing rotation of the bolt.

12. The demolition tool of claim 1, wherein the tooth holder further comprises a protective, extended portion engaging the front of one of the upper jaw and the lower jaw.

13. The demolition tool of claim 5, wherein each of the shear blade holders further comprises a blade holder aperture therethrough and wherein each of the shear blades further comprises a blade aperture therethrough, wherein the fastener engages the blade holder aperture and the blade aperture to removably mount the shear blade to the shear blade holder.

14. The demolition tool of claim 13, wherein each of the shear blades is rectangular, having four shearing edges, and wherein each of the shear blades is mountable on a shear blade holder to expose any of the four shearing edges to shear a work piece.

15. The demolition tool of claim 1, further comprising a stop formed in a shear blade holder to prevent a work piece from sliding out of the jaws.

A heavy duty, configurable shear/crusher demolition tool, comprising:

(a) an upper jaw, a lower jaw, and a pivot group connecting the upper jaw and the lower jaw;

(b) a plurality of tooth holders mounted on the upper jaw and the lower jaw;

(c) a plurality of teeth removably mounted to the plurality of tooth holders wherein the plurality of tooth holders further comprise a configurable number of tooth pockets receiving the teeth and fasteners mounting the teeth in the tooth pockets;

(d) a plurality of shear blade holders mounted on the upper jaw and the lower jaw; and a plurality of shear blades removably mounted to the plurality of shear blade holders wherein the plurality of shear blade holders further comprise mounting surfaces receiving a configurable number of shear blades and fasteners mounting the shear blades to the mounting surfaces.

17. A heavy duty, configurable shear/crusher demolition tool, comprising:

(a) an upper jaw, a lower jaw, and a pivot pin connecting the upper jaw and the lower jaw;

(b) a plurality of tooth holders mounted on the upper jaw and the lower jaw;

(c) a plurality of teeth removably mounted to the plurality of tooth holders wherein the plurality of tooth holders further comprise a configurable number of tooth pockets receiving the teeth and fasteners mounting the teeth in the tooth pockets;

(d) a plurality of shear blade holders mounted on the upper jaw and the lower jaw; and a plurality of shear blades removably mounted to the plurality of shear blade holders wherein the plurality of shear blade holders further comprise mounting surfaces receiving a configurable number of shear blades and fasteners mounting the shear blades to the mounting surfaces;

(e) a stop formed in a shear blade holder to prevent a work piece from sliding out of the jaws; and

(f) wherein the tooth holder further comprises a protective, extended portion engaging the front of one of the upper jaw and the lower jaw.

18. The demolition tool of claim 17, wherein each of the plurality of tooth pockets further comprises a flange with a flange aperture therethrough and wherein each of the plurality of teeth further comprises a leg with a leg aperture therethrough, the leg engaging the flange and the fastener engaging the flange aperture and the leg aperture to removably mount the tooth to the tooth pocket.
