ABSTRACT:
Two elongated members are coaxially movable relative to one another with one member rigidly attached to a working head such as an elongated wedge or the like. In one embodiment, the inner member is fixed to the working head while the outer member movably surrounds the inner member. The outer member is dimensioned so that its lower perimeter edge is small enough to allow the members to be reciprocated so as to drive the head into a log or other material without the outer member being held against coaxial reciprocal movement by the material. The members can be secured as for lifting, withdrawing, transporting, and the like with a flexible collar on the outer member for cooperating with a hole therethrough for gripping the inner member. The outer member can be fixed to the working head and the inner member reciprocally movable therein. Shock absorbing handles and an impact surface cushion insert are also shown which reduce jarring and fatigue in an operator's hands and arms.
