The blade (1) is inclined to the axis of the handle (2), and contains one or more recesses (9,9') between protrusions at its free end (4,5).At this end is a chamfer (6) inclined to the plane of the blade, and the edges (10) enclosing the recesses are radiused.The chamfer can form a knife edge tapering towards the free end, being formed only at the side furthest from the handle-mounting (3).Sawteeth, preferably three to eight in number, can be formed at one or both sides of the blade. The chamfer can reduce the blade thickness by up to 80% at the free edge
