Double Taper wedges have set the standard in the Pacific Northwest for plastic falling wedges for over 50 years. These wedges are made of extremely hard, high impact ABS plastic. The surface of this wedge is smooth except for the V shaped barbs. This specialty wedge helps prevent kickback in frozen wood. Wedges have fluorescent orange heads on a yellow body, so they are easy to see in brush. As with all wedges, use safety glasses when driving them.
