A garrote wire concealed within a string of decorative beads worn as a bracelet or necklace. The beads are machined from tungsten carbide and threaded on a 1mm monofilament wire with breaking strength of 400 kilograms. When deployed — unclasped and drawn taut between two hands — the wire cuts through unprotected tissue in seconds, and the tungsten beads provide grip points that prevent the wire from slipping through the operator's hands.

Rosary garrotes are Shelf craft — assembled by hand from industrial monofilament and machined beads, then disguised as costume jewelry. They are worn openly, passed through security checkpoints without comment, and carried in environments where no other weapon could enter. The Rosary exploits the most fundamental assumption of weapons screening: jewelry is not dangerous.

The weapon requires close physical contact and significant upper-body strength to deploy effectively, limiting its use to ambush or grapple scenarios. But its concealability is unmatched — a Rosary looks like a piece of inexpensive jewelry, weighs almost nothing, and shows up on X-ray as exactly what it appears to be: a string of metal beads. Only someone who recognizes the specific bead material and wire type would identify it as a weapon, and that requires expertise that most security personnel do not possess.
