An adjustable wrench in which a slidable jaw is biased away from a fixed jaw, toward a fully-open position, by the force of a biasing spring, and a pawl and ratchet mechanism locks the slidable jaw, against the biasing force of the biasing spring, in any selected one of a plurality of positions relative to the fixed jaw and enables selective release of the slidable jaw for movement to the fully-open position in response to the biasing force of the biasing spring.
