Abstract
A pivotal jawarm for a compression tool has opposite sides, a pivot pin opening therethrough, longitudinally opposite ends on longitudinally opposite sides of the opening, and inner and outer edges between the ends and on laterally opposite sides of the opening. A stress concentrator comprising aligned recesses in the opposite sides of the jawarm extends from the inner edge toward the pivot pin opening and provides a failure point at the inner edge for consistently initiating a fatigue crack at the failure point and fracture of the jawarm from the failure point to the pivot pin opening.
