Adamantite Chainsaw

The Adamantite Chainsaw is a tool/weapon that may be introduced in the 1.1 update. It is likely to be crafted out of Adamantite Ore.

Judging on the fact that it is a Chainsaw, and that the Adamantite Drill functions like a Pickaxe, the Adamantite Chainsaw might act as an Axe. This is however not confirmed as in a recent dev blog video, the Chainsaw is only seen used as a weapon.
