noun
braided cord
A traditional Japanese cord made by braiding threads, often used for decorative purposes, clothing fastenings, or craftwork.
着物の帯締めに打ち紐を使う。
I use a braided cord for the kimono sash tie.
この打ち紐は絹糸でできている。
This braided cord is made of silk thread.
組み紐 is a broader term for braided cords, while 打ち紐 specifically refers to a type made by a pounding or beating technique, often firmer and used for practical fastenings.
The term combines 打ち (uchi, 'striking' or 'beating') with 紐 (himo, 'cord'), referring to a traditional method of making cords by beating or pounding threads during the braiding process. The exact historical origin is uncertain, but it is a well-established craft term.
