Each digging tool was designed by Eric Wallace and then tweaked to perfection with extensive field testing by Reputable diggers throughout the U.S . The Shovel heads are sent out to be laser cut, CNC machined sharpened and then formed. Eric does the fabricatiing and welding himself. Therefore he has his hands on every single shovel that is made. Each weldment is then stress relieved and hardened at 50 rockwell. He also added the extra process of powder coating them in Vulcan Black and Blood Red to ensure all digging tools will last.
