A tool includes a handgrip having a chamber for rotatably receiving a handle and having one or more stop surfaces for engaging with the handle and for limiting the rotational movement of the handle relative to the handgrip. One or more blocks are secured to the handle and rotatably received in the handgrip. A fastener is secured in the handgrip and engaged through an oblong hole of the handle. One or more springs may recover the handle relative to the handgrip. A knob may selectively lock the handle to the handgrip.
