The Cow Hitch Variant which is also known as the Piwcih knot, is a stronger alternative to the Pedigree Cow Hitch.
The cow hitch is a hitch knot used to attach a rope to an object. The cow hitch comprises a pair of half-hitches tied in opposing directions, as compared to the clove hitch in which the half-hitches are tied in the same direction. It has several variations and is known under a variety of names. It can be tied either with the end of the rope or with a bight.
