The artillery loop [1] is a knot with a loop on the bight for non-critical purposes. The artillery loop must have the loop loaded or it will slip and contract easily. It is an inferior knot to the alpine butterfly knot, [2] possibly dangerously so, in that it can be yanked out of shape and turn into a running knot or noose. [6]

Contents

Budworth states that this knot is often described as being best suited to take a load on only one of the ends, but reliable information on which end is difficult to find. [7]

Tying the knot

Usage

The name harness loop derives from the fact that the knot was used when assisting horses on difficult terrain. [7] Similarly, the name artillery loop or artilleryman's hitch derives from the fact that it was used when hauling field artillery into position. [7]

Ashley appears to have illustrated or named the incorrect knot in this case. The butterfly knot, under the name Lineman's Loop, is shown and discussed as a distinct and specific knot throughout the rest of the book.
