One finger, one hole, no fuss. The Sport One-Finger Knuckle Duster slips over a single finger and leaves the rest of the hand free, which makes it an easy piece to carry, wear or pass to a training partner. Its matte gunmetal body carries a repeated SPORT stamp on both faces and a small lanyard hole at the crown for a cord or key ring.

Small Enough to Live in a Pocket

At about 78 g in zinc alloy this is a light, unobtrusive piece. It sits flat against the finger, so it disappears into a pocket, a coin pouch or a glovebox, and the smooth outer face means it will not snag on a lining or a strap. What weight there is sits at the crest, where it does the most good.

One Finger, Full Grip

Because the load rests on a single finger, the frame stays secure without a clenched fist. The hole is sized for a comfortable fit on an index or middle finger, and the body is formed as one piece so there is nothing to loosen or rattle over time. A lanyard hole at the crown takes a cord, and the matte finish keeps the whole thing low-key.
