Long nose locking plier

Abstract

A long nose locking hand tool having a pair of opposing jaw members, a fixed handle, a movable handle, and lever locking means therebetween for maintaining a toggle relationship between the jaws when in a closed position; wherein each of the jaw members comprises a jaw face having a total jaw length to average jaw height ratio of from about 6.5 to about 8.5 made of an alloy spring steel with a hardness range of from about 53 to about 57 Rockwell C, having a nominal parallel opening when they are spaced apart, approximately 3/16 inch, thereby enabling said jaw members to clamp a workpiece up to 3/16 inch thick. Furthermore, said fixed handle has an adjustment screw and a strike surface with an axis passing through said strike surface defining the direction of a line of force impartable to the hand tool; said pair of jaws further defining a bisecting axis formed by the angle of said jaws when closed against a workpiece, and the angle between said axes being less than 50.degree. when the gripping tips of said jaw members are in a closed position.
