Line splices are the strongest and most effective way of bending two lines together or forming a loop in the end of a line. The Back Splice is used to prevent a line end from unraveling as well as installing a “handle” in the end of a line. All splices are more difficult to make than knots, especially with braided line. The USPS Guide, Knots, Bends, and Hitches for Mariners , has excellent descriptions and illustrations of the common splices including the Eye Splice, the Short Splice, the Long Splice, and the Back Splice, as well as a detailed section on putting an Eye Splice in the end of double-braid line. The two most-used splices are the Short Splice and the Eye Splice.
