Block Classic Archery Target. The Classic Open-Layered Archery Target is designed to stop arrows with friction, not force. Patented open-layered design stops arrows with friction. Lets arrows enter between open, unglued layers of friction foam. The heat generated by high speed arrow penetration, along with friction, literally grabs the arrow shaft. In seconds, the heat dissipates and releases the arrow shaft making arrow removal as easy as it can get.
