A large slogging wrench used by a dwarf general. Some of the bolts used for larger structures are so heavy that even the sturdier dwarves have trouble tightening them. In such cases, the dwarves will rotate the wrench by continuously slogging the other side of it with a hammer. It is from this practice that the wrench takes its name, and not because it was originally intended to be used as a slogging weapon.
