Tinkers' Construct Edit
Cactus can be used as a toolmaking material in Tinkers' Construct. It has average durability and mining power, and has slightly increased damage because it has a base modifier of Jagged, which increases melee damage but lowers mining speed as the tool or weapon becomes more damaged. Cactus parts are made with wooden patterns.
