A military sword is not complete without the addition of a sword knot.
Originally used as a lanyard and an essential accessory to a fighting weapon, the knot is now tied to the sword hilt as a decorative embellishment.
Sword knots are of two main types depending on the uniform being worn by the officer. When wearing active service dress, the sword knot is a plain brown or black leather acorn and strap. Full dress versions are more elaborate creations of gold or silver with some patterns unique to a particular regiment or corps.
