Raidops Angry Caesar Knucks Brass Knuckles/Duster Keychain

Default size fits a knuckle width of 9.5cm/3.75 inches, I use 83.55% scale and I have 8.5cm/3.35 inch knuckles

Replica of a knuckle duster keychain from the chinese company raidops
Haven't applied any chamfer so it's probably not going to be very comfortable to use, it's vaguely dimensionally accurate
