Usage: The Sheet Bend is recommended for joining two ropes of unequal size. The thicker rope should be used for the simple bight. It works equally well if the ropes are the same size. This knot is considered by many to be an “essential” knot — So much so that Ashley listed it as the first knot in his canonical book.

ABOK: 1

Classification: Bend

Structure: Structurally, the Sheet Bend is related to the Bowline. When correctly tied, the two tails lie on the same side of the knot and is more reliable than if the tails lie on opposite sides.

Strength/Reliability: The Sheet Bend is more secure than the Reef Knot but can work loose when not under load. If the tails lie on opposite sides, the knot is known as a Left-Handed Sheet Bend and the reliability is decreased.
