Zane's Ice Spike is a Ninjago weapon, mainly wielded by Zane. It is a silver axe with a large, single-bladed head and a light blue gem set opposite the blade.
According to the official description, the weapon is named for the gem/spike, but it is not made of Ice. Instead, the spike is said to be made of a rare, nearly unbreakable material similar to diamond. The carving process is described as being slow and painstaking, but contributes to the weapon's effectiveness and beauty.
Ninjago.com Description
The spike was not actually made from ice, of course. It is a rare diamond-like material that is nearly unbreakable. The process of carving the spike is very slow and painstaking. But the result is stunning!
