|User(s)||Toa Metru Nuju (formerly)|
|Status||Transformed into Ice Pick|
The Crystal Spikes were Toa Metru Nuju's Toa Tools. They helped him to climb from building to building, and could control his power over Ice. When Nuju became a Toa Hordika, these were mutated into Hordika Teeth, but when Nuju was later cured, they changed back to Crystal Spikes. They were transformed into the Ice Pick after Nuju became a Turaga.
In the Toa Metru Nuju set, the Crystal Spikes could be attached to his feet to double as climbing cleats or snow shoes.
- In BIONICLE Heroes, Crystal Spikes are the second weapons Matoro uses, upgraded from the Ice Sword. They could later be upgraded to the Energized Ice Sword.
