What is "water knot"

n. a type of bend knot used to join the ends of tubular webbing, commonly employed by mountaineers to create a sling seat, but not considered to be as safe as the beer knot.

The water knot (also tape knot, ring bend, grass knot, or overhand follow-through) is a knot frequently used in climbing for joining two ends of webbing together, for instance when making a sling.
