The two Half-hitches Knot

The two Half-hitches is a type of knot, specifically a binding knot or hitch knot. It consists of an overhand knot tied around a post, followed by a half-hitch.

Equivalently, it consists of a half-turn around a post followed by a clove hitch of the running end around the standing part.

This knot is also sometimes referred to as a clove hitch over itself.
