ABSTRACT:
A manual wrench includes a plate-like member having a plurality of substantially equally spaced projections extending around the periphery of the plate-like member. A slot is formed between two projections. A handle can be friction fitted over one of the radially extending projections for increasing the amount of leverage that can be applied to the wrench.
