The Power Axe is the personal weapon of the Black Ranger.

To aid them in the fight against Rita Repulsa's monsters, the Power Rangers were each given a unique Power Weapon. It is a black, single-blade axe which can be used for blunt damage. The base of the axe can be slid downward towards the base, converting into a cannon-like weapon.

All five weapons could be combined to form, the Power Blaster which shot a powerful beam of combined energy to induce serious damage to a monster. The Power Axe forms the main portion of that weapon.
