A tool, such as an adjustable wrench, has an adjustment mechanism to allow the operator to alter the angle of the tool head with respect to at least a portion of the tool handle. The adjustment mechanism, in a preferred embodiment, utilizes a pair of wings, one or both of which may be pushed rearwardly along the handle to disengage the locking mechanism from the tool head to allow for an operator to alter the angle of the tool head with respect to the handle. In a preferred embodiment, the locking mechanism has at least two teeth which engage a toothed hub which faces rearwardly of a pivot point on the tool head and is held into position by a spring when not disengaged by an operator.
