A classic restraint with a distinct Darby mechanism.
The KUB 121 handcuffs follow a traditional Darby-style design, combining a rounded vintage form with a clear mechanical character. Their glossy finish gives them a striking appearance while keeping the silhouette clean and reduced.
Unlike modern ratchet cuffs, Darby handcuffs lock in a fixed position and are operated with the included screw key. This creates a deliberate handling experience and a consistent lock once secured.
The rounded shape supports comfortable wear, while the snap-style closure makes application straightforward before final locking with the key.
