With a tip for unsticking fused nuts and a hook for reaching buried cam triggers, the Black Diamond Nut Tool has an added bonus… a nifty bottle opener. You can now crack open a cold one at the end of a hot day. Plus, you'll be psyched to know that it is the lightest full-service nut tool out there.
