Title: Carbide cutting tool

Abstract: Disclosed is a cutting tool constructed entirely of a carbide material. The cutting tool is designed such that the front face is beveled to form a cutting edge along a top front end of the tool. Elongated sides of the tool between top and bottom surfaces converge along two different axes so as to converge in directions away from the cutting edge. This converging design provides the cutting edge at the widest portion of the tool even after the tool has been used and sharpened repeatedly.
