The "short" Double Harness bend with parallel ends

Discussion of the Double Harness Bend with Parallel Ends (ABOK #1421)

This bend is strong, secure, efficient (i.e., uses little cord), symmetrical, easy to untie (though, apparently, Ashley was unaware of how to untie it easily), has tails coming out of the same side, can be made stopper-flush, is quick and easy to make, and is attractive and conveniently sized. In the tests I’ve conducted, using waxed dental floss, it did not slip after repeating more than 100 hard tugs, while four of the popular bends did. It is untied easily by placing a thumb (or a thumbnail, if the cord is thin) in the middle of the knot’s SIDE and using the thumb as a pivot over which the knot can be bent. Bending the knot in this way quickly and easily loosens it for untying. If the tails of #1421 are reverse twisted, the knot’s top will take on a slightly different appearance, and the knot will be as secure as the popular bends tested; make the knot as in the diagram, however, and the knot will be MORE secure than the popular bends tested (which were Hunter’s Bend, Butterfly Bend, Ashley Bend, and Zeppelin Bend).

When making this bend, I think, “With the right line running above the left line; right goes over, under, under, and in between; left goes over, under, under, and in between.” When the knot has been made and tightened correctly, the top of it shows a type of letter-Z shape.

A similar “Short” and “Long” dressing of the point-symmetric Double Harness bend is shown at the attached pictures. ( One can see that the difference in length is even smaller than in the case of the Double harness bend with parallel ends ). At the “Short” dressing, where the tails of the two links overlap each other, the curvilinear paths followed by the lines are smoother.
