Tenacious II

Tenacious II is a high damage unique melee weapon presumably crafted by Atlas, which is later on obtained by Chevelle.

Characteristics
The weapon consists of a dual-sided metal blade that is serrated on the spine, and sharpened on the other edge. It has a strong curve and point on the end of the blade. The handle also appears to be made from a type of strong metal. While Tenacious II is heavy, it does considerable damage and is very durable: resisting most damage to itself.
