Sword Knot Navy
Sword “knot” is in fact a loop of leather or other material secured to the sword hilt.
Before an engagement the swordsman wraps the loop around his wrist to prevent loss of the sword should he need to relax his grip (to control his horse, for example) or if the weapon is struck from his grasp. From these utilitarian origins, the sword knot has gradually evolved into its ornamental and distinctive form today.
