Usage
The Sheet Bend is an essential knot used for joining two ropes of unequal size, though it works equally well with ropes of the same size. The thicker rope is typically formed into a simple bight, while the thinner rope is passed through and secured. The Sheet Bend is especially popular in sailing, climbing, and general utility work due to its simplicity and strength. The Sheet Bend is considered by many to be an 'essential' knot — So much so that Ashley listed it as the first knot in his canonical book.
Warning
Verify tying technique with a skilled instructor where knot failure could cause property damage, injury, or death.
History
The Sheet Bend has its origins in sailing and maritime traditions, where it was commonly used to fasten ropes, or "sheets," to sails. In this context, a "sheet" refers to a line attached to the lower corners of a sail, used to control its angle to the wind. The knot’s name likely stems from this nautical application. Historically, the Sheet Bend was mentioned in David Steel's "Elements and Practice of Rigging and Seamanship" (1794), but evidence shows it was also used by Neolithic peoples for tying fishing nets. Another name for the Sheet Bend is the "Weaver's Knot," reflecting its use in textile mills for repairing broken threads in the warp, the set of lengthwise threads held taut on a loom during weaving. Even today, weavers continue to use this knot when correcting broken threads in the warp.

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. Additional security can be gained by adding a second turn which forms a Double Sheet Bend. The Sheet Bend's strengths lie in its simplicity and non-jamming properties, making it both easy to tie and untie.
