Bowline on a Bight
Bowline on a bight (referenced in The Ashley Book of Knots) creates a secure loop in the middle of a length of rope. It is a variation of the bowline knot that looks similar but is made with a single strand of rope. If you want to make a dependable loop when neither end of the line is available, this is one knot you can vouch for.
