  • Patent number: 6481691
    Abstract: A fastener puller capable of removing fasteners embedded in a material having a surface, the puller having a handle, a horn having a wedge, connecting means form mounting the horn to the handle and an elongated ram slidably mounted with respect to the handle. As the ram is moved along a slide path, the ram abuts the horn causing the wedge to be forced underneath the head of a fastener.
