Abstract
A hand tool or wrench with a ratcheting mechanism. The wrench includes a number of components such as an abutting block and a pawl for use in a bistable ratchet operation. The wrench includes a ratchet mechanism that provides stable seating of the components, so that the mechanism is securely retained in a driving mode, as well as enabling a user to select a driving mechanism with ease so as to improve work efficiency.
