The true lover's knot is the name for several knots, incluing the Middleman's knot, Fisherman's knot and Shamrock knot. The most popular version, the Middleman's knot, is actually a bend created by interlacing the loops from opposing overhand knots with the opposite line. This knot is very similar to a two stranded Matthew Walker's knot, the difference being that in Matthew Walker's knot the standing ends and the working ends are on the same sides, and in this knot they are opposed.
