The overhand knot is one of the most basic knots, and forms the basis of many others, including the simple noose, reef knot, fisherman's knot. The overhand knot is a stopper knot, especially when used alone but is a jamming knot. It should be used if the knot is intended to be permanent.
The overhand is the simplest of the single-strand stopper knots, and is tied with one end around its own standing part, its purpose being to prevent unreeving. The half knot is a binding knot, being the first movement of the reef or square knot. It is tied with two ends around an object and is used when reefing, furling, and tying up parcels, shoestrings, and the like. The half hitch is tied with one end of a rope which is passed around an object and secured to its own standing part with a single hitch.
It is used to:
- prevent the end of a rope from unravelling.
- prevent the end of a rope from pulling through a pulley.
