Old school knuckle duster

Here's a knuckle duster, that was made several weeks ago already..

It is made from 10 millimeters thick alluminium, is 54 millimeters high and 102 millimeters wide.

Curved palmrest gives good grip in hand however, the palmrest should be slightly longer for even better griup.

Finish is polished, by size fits to my hand perfectly or slightly small.

This is the knuckle duster I ever wanted and is the reason that I started to interest in them.
