Abstract
A tool with a drive lug having groove formed on the drive lug to promote failure of the drive lug before internal component failure. The groove has a predetermined diameter and is formed on the drive lug or ratchet square to cause failure of the drive lug, due to a torsional ductile fracture, before any internal component failure of the tool, such as, for example, gear and/or pawl failure in a ratchet wrench.
