Its only a bottle opener

[gregarat]

How so?

It works on the same principle as brass knuckles. Except that it only one ring, not four rings. The opposite end has almost as much surface on the palm as Brass knuckles.

When I tested it on a 2x4 board it did more damage to the board than a naked knuckle would ever do. I would assume it does allot less damage to my wrist and or palm, than a naked knuckle would receive.
Although I didn’t hit it with everything I had.
