Introduction: A Two-strand Paracord Lanyard Knot
As knot #802 in 'The Ashley Book of Knots', Ashley says it has "...somewhat the character of the diamond knot.", found on page 145 of the book, and is a two-strand version of knot #758, Captain Charles W. Smith's Sinnet Knot.
A couple of examples that I show of the knot have additional gaucho knots tied with 0.9mm cord around the end strands, for an added decorative look.
