ZETA1.0 Knuckle Duster

It’s compact enough to disappear in my palm yet the grip holes are spaced perfectly for a solid hold. The anodized surface gives it a sleek, almost premium feel that I wasn’t expecting at this price point.

The machined finish on the knuckle duster is surprisingly smooth, no sharp edges at all. I've been carrying it daily for a week and it fits the hand perfectly, solid weight without being bulky.

Carried it around on my keys for a week and the finish still looks brand new—the machining on the knuckle duster part is impressively clean. It's got a nice heft to it that makes it feel solid in the hand, and the multi-tool aspect is a clever bonus I didn't expect to use as much as I do.
