Boxer patent knuckle duster

That's being my latest aluminum knuckle duster, which I made. It's a copy of very old German knuckle duster, Boxer Patent.

I made it from 12 millimeters thick aluminum, measures 102 milimeters in wideness and 60 in height.

Palmrest is pretty curved, so it fits to ym palm very good.

It has kind of halfpipe on each side milled out, so it looks even more like the original.

On fingertops are 4 pyramid style spikes, which are very sharp.

Finish is sanded silver matt, I think it came out best way this way.

I'm thinking about putting words "BOXER" and "PATENT" on each side, but I don't know how, I might laser-engrave it one day, I don't know how I'm going to solve that problem.
