The claw clubs were a pair of mace-like weapons that served as Onewa's Toa tools when he was a Toa Hordika.1, 2, 3, 4, 5, 6 Although Onewa lacked elemental powers as a Toa Hordika, he could use his claw clubs to charge his elemental stone Rhotuka spinner, which could significantly increase the strength of its effects.1, 2, 3, 4, 5, 6 In order to do this, Onewa needed to hold up his claw clubs, launch a Rhotuka spinner from his back, and mentally will it to hover in place in between his claw clubs while they charged the spinner, before releasing it again. It took only a couple of seconds to charge a spinner up significantly.7 Onewa could not charge anything else with his claw clubs other than his own Rhotuka spinners.8, 9 Onewa could also use the claw clubs for climbing2 or to hurl stones with incredible accuracy.1, 2, 3, 4, 5, 6
Onewa's proto pitons mutated into the claw clubs when he was mutated into a Toa Hordika. When Keetongu cured Onewa, the claw clubs turned back into the proto pitons.CN
