#sheet bend

A left-handed sheet bend creates a much weaker connection, especially under moderate loads.

Sheet Bend [Explained]

#1 The ubiquitous sheet bend, used to join two ropes, especially of different thickness. In these photos, both free ends are on the left. Most people would probably consider this the same knot as #2, the weaver's knot, but Ashley declares:

Figure-of-Eight Knot ;; stops a rope from running through an eye or block

Bowline Knot ;; used to make a temporary loop/eye in a rope, esp. when used as a lifeline

Clove Hitch ;; used to secure rope to spar or rail (tightens if pulled from other side)

Timber Hitch ;; used to secure end of rope to a spar or cargo (i.e. sack). Can be used in conjunction with half-hitch.

Rolling Hitch ;; used to secure rope to spar when pull is from either side

Round Turn and Two Half Hitches ;; used to secure heavy loads to ring or shackle. Can also be released quickly.

Fishermen's Bend ;;  Alternative to round turn and two half hitches. Often used to secure rope/hawser to ring of anchor. Is not easily undone. Tighter if pulled.

Sheet Bend ;; used to secure end of rope to small ring or eye. The more secure/complex version of this knot is the double sheet bend.

Hawser Bend ;; used to join two steel/rope hawsers to become similar to two linked bowlines. Ends of ropes are usually seized/tied to standing part of rope.

The sheet bend (also known as weaver's knot or weaver's hitch) is a bend, or, a knot that joins two ropes together. The sheet bend is structurally similar to the bowline. It can be tied quickly, and is considered one of the sailor's essential knots. Doubled, it can effectively bind two different types of lines securely together, although may work loose when not under strain.

To tie, form a loop in the thicker rope (red) and hold it in one hand. Pass the thinner rope (green) through the loop and behind the (red) tail and standing ends in that order. Finally, tuck the smaller rope under itself to finish the knot.

Make sure the two ends are on the same side of the knot. If the ropes are of very different thickness, take the working end round the bight and under itself twice to form a double sheet bend.
