ABSTRACT:
A nail puller defines an elongated body having a static gripping jaw formed therein and a handle socket for receiving a handle. An elongated handle is threadably received within the handle socket. A moveable jaw is pivotally attached to the puller body and defines a jaw blade and an extending lever arm. A limit stop is interposed between the lever arm and the puller body to provide a limit on the closure of the static and moveable jaws. The puller body further defines a drive receptacle for receiving a drive portion of a lever-type tool such as a drive ratchet as an alternative for the handle. In an alternate embodiment, an additional handle socket is defined by the puller body having an angular orientation different from the first handle socket permitting the use of the removeable handle in alternate configurations.
