Ring hitch (double-ended)

Not strictly an angling knot, this ingenious hitch will nevertheless link two eyes, rings, or

swivels by means of an endless band, provided it can be passed over one of them. At first glance
it appears to be an impossible knot, but it is actually quick and simple to tie. Perhaps it was once
a medieval harness-makers’ trick, but it was rediscovered recently by Joe McNicholas of

Pennsylvania.

Pass one end of the sling or strop through one ring and then tuck it down through itself to make a
simple ring hitch (1). Take the bight through the second ring, bring it up beneath the crossing loop,
and then pass it completely over the first ring (2). Then take the working bight down behind
everything to interlock with the initial ring hitch (3). This hitch (4) works equally well (large- or
small-scale) in cord, tape, and webbing, or even in a rubber band for luggage labels.
