Mad Rock's Busta Nut tool is the latest in nut busting technology. It features a built in carabiner for easy clipping, eliminating the need to carry an extra carabiner. It also has a keeper strap hole to make sure you don't drop Busta. A flat back makes palm pounding those nuts painless. Not to metion the built in beer bottle opener. Its everything you'll ever need in a nut tool.
