ABSTRACT:
Two elongated members are coaxially moveable 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 moveably 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, etc., with a particularly advantageous form of the securing means being 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 moveable therein.
