Proto Pitons

The Proto Pitons were Toa Metru Onewa's Toa Tools. They allowed him to swing from building to building and climb them with ease. They could also channel his Stone Elemental Powers and control over Stone. These were lost when [Onewa] transformed into a [Hordika]

Set Information
In the Toa Metru Onewa set, the Proto Pitons' chains were made of slightly softer plastic, allowing them to swing a bit.
