Cleaver

A meat cleaver is a large, most-often rectangular knife that is used for splitting or "cleaving" meat and bone. A cleaver may be distinguished from a kitchen knife of similar shape by the fact that it has a heavy blade that is thick from the spine to quite near the edge. The edge is sharply-beveled and the bevel is typically convex. The knife is designed to cut with a swift stroke without cracking, splintering or bending the blade.
