A Disc-detainer (or disc lock, disk lock) is a lock design that uses rotating discs as locking components. In most designs the discs interface with a sidebar when properly rotated to allow them to actuate the locking bolt. Disc-detainers are primarily associated with Abloy locks, but ABUS, Kryptonite, and many knock-off brands have begun making them, too.

This lock picks set contain 1 x Disc Locks Pick and 1 x rear tension pick (without the lamina lock), can be used to open the adamantine lock.
