Method of creating a loop in the end of a rope
the knot

The eye splice is a method of creating a permanent loop (an "eye") in the end of a rope by means of rope splicing. The Flemish eye is a type of circular loop at the end of a thread. There are several techniques of creating the eye with its knot tied back to the line, rope or wire.

An eight strand rope consists of two left twisting and two right twisting pairs. Make sure the left twisting strands are fed below left twisting strands, and right twisting strands below the right twisting ones. Work systematically with different tape colours to keep from getting lost in the mess of strands. An eight strand square plaited rope can be used as mooring line or anchor rode.

This technique is mostly used for Dyneema ropes. The principle of a Dyneema eye is a core to core splice, in which a length of at least 60 times the diameter of the rope is taken back into itself. DSM advises using 60 times the diameter for coated Dyneema, and 100 times the diameter for uncoated Dyneema. For 6mm coated rope, this would mean 36 cm. Under tension the rope will pull into itself tightly, which produces a strong eye. One can pull out the eye when the rope is not under tension, unless one makes a lock splice (also called brummel splice).

In ropes with a polyester (or nylon) core, both the core and the cover are needed for strength. Instructions are published in Literature and reference sources typically attribute only a 5% strength decay for a properly tied splice. Technically, a perfectly tied splice retains 100% of the original strength of the rope but in practice this is rarely the case. Destructive testing of rope in manufacturing facilities makes use of a professional and spliced eyes for connecting the rope to the testing apparatus.

The bowline is a quick, practical method of forming a loop in the end of a piece of rope. However, the bowline has an awkward tendency to shake undone when not loaded. The bowline also reduces the strength of the rope at the knot to ~45% of the original unknotted strength.
