Abstract

A slip-joint pliers has crossed pivoting levers joined at pivot portions thereof by a flat-sided bolt extending through openings in the levers and engaged with a nut, one of the openings being elongated and generally dumbbell-shaped to accommodate the slip-joint movement. The pivot portions of the levers have flat facing inner surfaces, in each of which is formed a single-level spring recess surrounding the associated opening, each recess having a peripheral side wall and a flat planar bottom wall extending from the side wall to the associated opening. A helical torsion spring is seated in the recesses and encircles the bolt and has tangent ends respectively engageable with straight bearing portions of the recesses.
