A torque-applying tool by means of which the frangible protruding ends of concrete wall form tie rods with conventional button-heads and breakbacks may be twisted from the embedded medial regions thereof. An eccentric jaw action is effective in the direction of torque-application to afford a high mechanical advantage for tie rod clamping, coupled with high torque leverage, while a spring-biasing action, coupled with an overlay flange on the clamping jaw permits one-hand manipulation of the tool.
