Abstract

See full text

A star-type wrench includes a shank, a first operation portion mounted on a first end of the shank, and a second operation portion mounted on a second end of the shank. The shank is formed integrally to have a star-shaped outer diameter. Thus, the shank has a star-shaped outer diameter so that when the first operation portion or the second operation portion is broken, the first operation portion or the second operation portion can be removed from the shank, and the shank can function as an auxiliary operation portion and can be reused and operated successively.
