It is quick and easy to tie, and is considered so essential it is the first knot given in the Ashley Book of Knots. Additionally, it is one of the six knots given in the International Guild of Knot Tyers' Six Knot Challenge, along with the clove hitch, bowline, reef knot (square knot), round turn and two half-hitches, and sheepshank.
The sheet bend is related in structure to the bowline; like the bowline, it has a tendency to work loose when not under load. For increased security, it is sometimes recommended that one add another turn in the smaller end, making a double sheet bend; in most cases, however, a single sheet bend should suffice. The becket hitch is another structurally similar knot.
As a bend, its advantages lie in its simplicity and non-jamming properties.
It is commonly taught in Scouting.
