The Climbing Chain was a tool used by Toa Inika Hewkii. It could be used for rock-climbing as well as channeling his power of stone thru it. The chain was attached to the bottom of Hewkii's Laser Axe. When Hewkii became a Toa Mahri, the Climbing Chain was transformed into Electrified Chains.
- They were first released with the Hewkii Inika set in 2006.
