A reduced arc box end ratchet wrench or ratchet drive wrench utilizes a multiple pawl ratchet assembly comprised of a body having an insert cavity to enclose critical components of an insert that is secured within the ratchet assembly. The insert is set into the wrench body and includes a plurality of pivoting pawls. Each pawl comprises a lever arm with ratchet engaging teeth. The pawl arms are positioned relative to the ratchet wheel to create “pawl swing arcs” and “reduced ratcheting arcs” to alternately or successively engage a portion of the teeth of a ratchet wheel at all times. This configuration allows smaller degrees between ratchet teeth and a smaller wrench rotation that is otherwise required to apply torque.
