Battendome 罰点留め
An X-shaped friction that locks lines which cross perpendicularly or meet in a T, often seen at the top wrap of a gote; in English the X-friction.
Shibari Study’s glossary describes battendome (罰点留め) as a sturdy friction in the shape of an X that locks together lines which cross perpendicularly or meet in a T. It is common at the top wrap of a gote, and its English name is X-friction. Andrea Ropes calls it a cross friction and gives as an example the friction that closes the upper wrap of box ties in the styles associated with Osada, Kanna and Kinoko. It is one of several named frictions, which hold rope in place without a knot.
