KUB Steel Restraints

Heavy, mirror-polished steel with a hold you can feel. KUB restraints carry real weight and real locks: working snap locks and push-in keys, never decorative.

Our KUB range brings together more than 20 pieces, including classics you rarely find elsewhere: Darby-style handcuffs and legcuffs, the rigid Irish 8, hand and neck pillories, shrew's fiddles and lockable steel collars. The mirror finish is only truly possible on solid steel, so it also tells you what is underneath. The pieces stay comfortable to wear despite their weight, whether you explore solo or with a partner.

Before you choose, take a look at How to Measure: Metal Gear for the right fit, and read more about the maker in The Makers We Carry.
