Seismic Pickaxe

The Seismic Pickaxe was Avak's one of tools. One end of it was a pickaxe and on the other there was a jackhammer. Both ends of the weapon could simply be used for destruction.

Trivia
In the Piraka/Toa Inika Animations, the Seismic Pickaxe is shown releasing powerful energy blasts, but that is not an actual function of the weapon.
