The overhand knot is one of the most fundamental knots and forms the basis of many others including the simple noose, overhand loop, angler's loop, reef knot, fisherman's knot and water knot. The overhand knot is very secure, to the point of jamming badly. It should be used if the knot is intended to be permanent. It is often used to prevent the end of a rope from unraveling.

Tying

There are a number of ways to tie the Overhand knot.

  • Thumb method - create a loop and push the working end through the loop with your thumb.
  • Overhand method - create a bight, by twisting the hand over at the wrist and sticking your hand in the hole, pinch the working end with your fingers and pull through the loop.

Knot theory

If the two loose ends of an overhand knot are joined together (without creating additional crossings), this becomes equivalent to the trefoil knot of mathematical knot theory.

Overhand knot in paper-folding

If a flat ribbon or strip is tightly folded into a flattened overhand knot, it assumes a regular pentagonal shape.[1]
