Bull Hitch
The Bull hitch is a knot with similar utility to the Cow hitch/Lark’s head knot. Both are used to attach cord onto items, be it buckles, rings, carabiners, etc. The Bull hitch is less prone to slipping and is defined by an “X” shape at the top. So if you want to spice your projects up or just want a new, practical knot this may be a nice knot for you.
