Loops

Loops are often employed as hitches, or they may be used in

climbing, caving, and rescue operations to create a fixed loop or

loops (as in the many variations on the bowline). Other loops offer a

slide-and-grip function (for instance, the Tarbuck knot), a noose

effect (the tucked double overhand loop), or a loop at the end of

fishing line (the Bimini twist).
