Tiny, round and easy to misplace on purpose: the Mini Ring One Finger Knuckle Duster is a 31 x 26 x 5.6mm zinc alloy ring with a single finger hole, about 10g, that rides on a keychain or a bag charm. Sold as a random set of 2 or 5 so you can stash one everywhere.

A Knuckle That Fits a Finger

The 20mm finger hole is sized for an index or middle finger, turning the little ring into a discreet impact tool that stays on the hand. Zinc alloy keeps it light and weatherproof, and the compact size means it hides among coins and charms until you close your fist.

Spread Them Around

Because they are sold in twos and fives, these are the kind of item you drop into every bag, every car, every drawer. A 10g knuckle is no burden, and having one within reach is the whole point.
