I started with two 5 foot lengths of 2mm dark brown round leather cord, centers of the cords looped over the snap hook/swivel clip, tied a lanyard knot with two strands and the other two through the center of it.
Tied a 4 strand round braid for about 14 inches, made a single crown sinnet at the end of the round braid, putting the Niteize S-Biner through the crown sinnet.
Then continued the crown sinnet back up around the round braid for about 1.5 inches and finished with a crown and wall knot, tucking the ends back down into the knot before trimming off the excess.
The Swiss Army knife is a Wenger Evogrip 18.
I'd done another with paracord last year, but figured one in leather would be a little different...
