Knuckle Duster

thingiverse

I've taken the old knuckle duster and given it a major overhaul, making it even more effective. This new design is tailored to fit my hand perfectly. I usually wear a large-sized glove to get an idea of its size, but this one has been specifically shaped for left-handers. If you flip it around in your CAD program, you can easily print out a right-handed version.
