Wooden Knuckles.

Being that brass knuckles are illegal, it was only a matter of time someone would make them out of something else. These bad boys are hand-crafted in Nashville, Tennessee by "woodworking gangsta" Mitch Roberson. They're made out of walnut and measuring 4.5" x 2.5". Pretty sweet.

You can purchase them HERE for $40.
