Double-column tie
A cuff binding two limbs or objects together, with a cinch passing between them that separates the columns and locks the wraps.
A double-column tie joins two columns, for example two wrists, a wrist and an ankle, or an ankle and a chair leg (Autostraddle). What distinguishes it from simply wrapping two limbs together is the cinch, kannuki in Japanese: rope that passes between the two columns and catches the wraps on the other side (Rope365; Anatomie Studio). Shibari Study notes that the cinch divides the cuff into two openings and keeps it from rotating around the limbs, and Anatomie Studio says it stops the tie from slipping. As with a single-column tie, the cuff is meant to hold a fixed size rather than tighten, and Autostraddle cautions against hanging a partner’s weight from tied wrists.
