Abstract
A manually operable tool, such as a tube cutter, having a working element carried on a carrier adjustably positioned on a mounting element. An improved arrangement of threaded advancing structure and selectively positionable pawl structure is provided to permit automatic release of the pawl at opposite ends of travel of the carrier for facilitated use of the tool. Automatic release of the pawl is effected by means of the provision of spaces at the opposite ends of the carrier thread permitting a biasing spring to reposition the pawl suitably for quick, nonthreading reverse movement.
