An axe or hammer includes axe head or hammer head with assembling blind hole and a handle, wherein the bottom part of the assembling blind hole is averted tapered shape, and. the part of the assembling blind hole, which is away from the bottom part of the assembling blind hole and is above the middle part and below the top part of the assembling blind hole, has a tubular shape. In the assembling blind hole there is an 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 locates between the blind hole and the inverted taper part of the wedge, in the course of assembling axe head or hammer head and the handle, due to inverted wedge producing great compressing force, the axe' or hammer's resistance to separating is increase with great extent, its reliability is also enhanced, and the life of validity is prolonged over 2 times than the known axe or hammer.
