Abstract
A long nose locking hand tool having a pair of opposing jaw members, a fixed handle and a movable handle and lever locking means therebetween for maintaining a toggle relationship between the jaws when in a closed position; and wherein each of said jaw members comprising a jaw face configuration having a total jaw length to average jaw height ratio of from about 6.5 to about 11.5 with a through jaw hardness range of from about 53 to about 57 Rockwell C, with said jaw members made of an alloy spring steel, said jaw members having a nominal parallel opening when they are spaced apart, no greater than about 1/4 inch, thereby enabling said jaw members to clamp a workpiece therebetween with parallel jaw faces by flexing to the parallel condition when closed and returning to their original unstressed state when released of clamping pressure. A long nose locking hand tool having a pair of opposing jaw members, a fixed handle having an adjustment screw, and a movable handle and lever locking means therebetween for maintaining a toggle relationship between the jaw faces of said jaw members when in a closed position; and wherein said fixed handle having a strike surface, and having an axis passing through said strike surface defining the direction of a line of force impartable to the hand tool; and said pair of jaws further defining a bisecting axis or line formed by the angle of said jaws when closed against a workpiece gripped therebetween; and the angle between said axes being less than 5.degree. when the gripping tips of said jaw member are in a generally touching or closed position.
