The Busted Knuckle Logo is cool, but what if we morphed it into a skull? Nailed It! The knucklehead logo is for the more hardcore gearhead. We work all night in the shop to a symphony of heavy metal, grinders, and welders. Let everyone know you are a hardcore Busted Knuckle Fan aka Knucklehead by putting one of these Knucklehead Decals on your rig. Available in a ton of colors and sizes to match whatever it is you are working on. ROCK ON Knuckleheads!
