It uses leverage from a triangular fulcrum that backs onto the blade and is ideal for digging trenches, holes, levering out tree roots, heavy rocks and pavers. The Power Bar is an integrated tool that does the work of a crow bar, spade and mattock. Its unique see-saw action multiplies the working force by up to 6 times. 10 Year Guarantee.
