A Water Knot (also called a 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.
To Tie a Water Knot:
| Tie a normal overhand knot, leaving at least a 6 inch tail. Make sure the webbing is flat, not twisted. |  |
| Insert the other end of the webbing where the tail comes out. |  |
| Follow the webbing around the knot. |  |
| Go back through the knot to the other side so you have tails sticking out both sides of the knot. |  |
