Abstract: A tool for removing slack in wire fences and the like includes a shank having a handle at one end and a first slot extending axially into the other end for engaging a fence wire. A second slot extending axially into the other end of the shank and angularly offset from the first is adapted to receive the bail of a generally rectangular wire clip. The shank includes grooves extending longitudinally from the second slot to engage the legs of the wire clip. The handle is rotated to wrap the wire about the other end to remove slack in the wire. The legs of the wire clip are then wound about the fence wire adjacent to the wrap to retain the wrap in the fence wire.
