Most sailors prefer the back splice’s symmetry and firmness to prevent unlaying when ending a line.
To make a back splice, razor-cut the end of three-strand laid nylon line. Unlay 12 to 14 inches of line, and apply masking tape to each strand to form points.
Cast a crown knot with the unlaid strands, and tighten by pulling and twisting with the lay (Figs. C and D).
Make a total of five sets of the following tucks:
A. Pick any of the three end strands and go under the adjacent working-part strand.
B. Watch for two parallel strands on the working part (railroad tracks); go over the first and under the second of these strands.
C. Turn the entire working part, and go over the first and under the second of the working-part strands with the third end strand.
D.–H. Pull each strand tight, paying attention to keeping a tight lay. Continue this pattern and shape the splice with your fingers as you go.
I. & J. For decoration, end the back splice with a wall and crown knot, pulling it tight with pliers and hiding the ends by heat melting (dimpling).
