Sheepsfoot blades are like reverse tanto blades. The unsharpened edge bends at an angle somewhere near the tip, and it slopes down to the point of the blade. Its sharpened bevel is a long, straight edge from the handle to the point. Wharncliffe blades have the same straight and unsloped sharpened edge, but the spine slopes towards the angled portion near the tip. The sheepsfoot and Wharncliffe blades offer a long cutting surface, but the spine’s steep angle towards the point makes piercing close to impossible.
