Surgeon's Knot
This knot is usually tied with twine. The Surgeon's Knot is a modified form of the reef knot, and the extra turn taken in the first tie prevents slipping before the knot is completed.

Sheet Bend
Also known as Weaver's Knot, and is used aboard ships for joining small or medium sized ropes.

Timber Hitch
This knot is very useful for hoisting and towlines, and holds well without slipping or jamming.

Fisherman's Knot
The Fisherman's Knot is probably the strongest known method of joining fine lines, such as fishing lines.

Figure-Eight Knot
This knot is used at the end of a rope to temporarily prevent the strands from unlaying.

Clove Hitch
Also known as Builder's Hitch because of its wide use by builders in fastening staging to upright posts.

Reef Knot (or Square Knot)
If tied with two ends of unequal size, or if one end is stiffer or more slippery than the other, it is bound to spill. Under no circumstances should it be used as a bend. (A bend is tying two ropes together.) There have probably been more lives lost as a result of using a SQUARE KNOT as a bend.
