Deathmatch Duel Rope
A Deathmatch Duel Rope, is a device similar to handcuffs that is attached to two Duel Disks. The Duelist who loses has their Duel Disk destroyed. They were used by Kalin, Yusei, Crow, and Jack while they were members of The Enforcers, and can be seen in many flashbacks, including when Kalin rescued Yusei by using his Duel Disk cuff. Crow also used one against Lazar.
