Sailmaker’s Whipping

This is one of the most secure knots around and does not easily get
damaged by unwinding. It’s perfect for three-strand ropes, and has grooves
that other knots may not have. Frapping turns differ—so you have to be
mindful of what you’re going to use the knot for, and it’s also best that you

burn the end for more security.

Instructions:

1. First, take the twine and thread it between the strands.
2. Then, wrap the longer part of the end around the rope.
3. Let the longer end pass through the strand—whether up or down a

groove, and then let the shorter end pass down—whether up, down,
or under.
4. Use a square knot to tie the ends with, and then pull them down or

cut them to secure the knot.
