sword knot
Sword knots are decorative cords or straps that are attached to the hilt of a sword. They are used to help secure the sword to the wielder's wrist while in use, preventing the sword from being dropped or knocked out of the hand during combat. Sword knots are often made of braided leather or silk and can be intricately designed with tassels, fringe, or other embellishments.
In addition to their practical function, sword knots also serve a ceremonial or decorative purpose, adding a touch of elegance to the overall appearance of the sword.
