Earthshock Drills are Toa Whenua Metru's Toa Tools. With these he could channel his elemental powers and use them for other things. He could also use them for Melee combat. He lost them when he became a Toa Hordika but regained them when he became a Toa Metru with the help of Keetongu. He has now lost them forever because he is a Turaga.
