ABSTRACT:
A handtool is disclosed particularly adapted to engage concrete forms for prying the same loose from the concrete after setting. The tool includes a gripping mechanism carried on a tool frame, the gripper mechanism enabling the lip portion of the concrete form to be gripped or clamped during the prying operations to maintain the engagement of the tool with the concrete form. The tool frame includes a support member for the gripper mechanism extending transversely to the tool handle which provides leverage for prying the form while it is engaged with the gripper mechanism. The gripper mechanism consists of a self-engaging cam clamp element pivotally supported and spring-biased to the engaging position with a release handle provided for releasing the grip from the form.
