I put a for grip on a rilfe that had a detatchable pair of spiked knuckles. I thought I would never live that down. At the time it just looked like a cool novelty item. After a few days it just looked plain stupid. However, I have a wicked set of spiked brass nuckles. On shot to face with those bad boys and you won't want another. That I can guarantee. I just found it the other day. I thought I had lost it for a little while. My kids thought they were the best thing since sliced bread. I took a ton crap from some members on here. Those spiked nuckles make a good addition to my bug out bag.
