Abstract
Standard flex-head wrenches and other standard wrenches having a head or fastener end-working portion are improved by adding a second and even third joint within the handle portion of the wrenches. The additional joints may comprise the standard ball bearing detent and mated groove pinion portion alone in structure or in conjunction with a locking sleeve, which aids in biasing the handle in any number of predetermined positions.
