Abstract
A tool, such as fixed-joint pliers, has first and second levers which are movably joined. The levers are joined at a joint comprising a housing and a coupler. The housing is defined by a first housing portion of the first lever and a second housing portion of the second lever. The housing has an interior area which houses a biasing member, such as a torsion spring. The coupler may comprise first and second bushings which extend through a passage through the housing and the torsion spring therein, and a male fastener which extends through one of the bushings and into engagement with the other bushing. The pliers have a thin profile and are biased to an open position for use.
