Usage

History
The Double Overhand is called the Blood Knot when used on a cat o' nine tails or on the snapper of an ox whip. A cat o' nine tails is a type of whip made up of nine knotted cords. Historically, the "cat", as it is sometimes called, has been used for severe physical punishment within the Royal Navy and British Army, and as a judicial punishment in various countries.
