An axe or hammer includes axe head or hammer head with assembling blind hole and a handle, therein the bottom part of the blind hole is inverted tapered, the shape of the middle part or the top part is tubular. In the assembling blind hole there is a inverted wedge whose shape corresponds with the shape of the blind hole, the handle is tubular, whose front part for assembling locates between the blind hole and the inverted taper part of the wedge. In this invention, because the front part of the handle locates between the blind hole and the inverted taper part or the wedge, in the course of assembling axe head or hammer head and the handle, due to inverted wedge producing great extrusion force, the axe' or hammer's force to separate is increased with great extent, its dependability is also enhanced, and the life of validity is prolonged over 2 times than the known axe or hammer. |
