The Swiss Army pocket knife shown with the lanyard is the
Wenger Evo EDC Knife (Evolution S13) that I received from
County Comm. This model is unusual for a SAK of this size, with
having a locking 2.5 inch main blade using a push button release mechanism. Anyone that's ever had a slip joint type pocket knife blade accidentally close up on 'em while cutting will appreciate the added security of a locking blade.

A recent YouTube
video from JD of TyingItAllTogether(TIAT) mentions what he's been up to lately, along with the gift of a
link
to instructions for the Back-to-Back Bar, a selection from his next
book, 'Paracord Fusion Ties (Vol.I)' which is due out this summer.

I followed the tutorial to learn the knotting pattern, a variation of the cobra stitch/Solomon bar/Portuguese sinnet, but added a snap hook and started off with 10 feet each of olive drab and black
paracord. The finished length of the completed lanyard with attachment is one foot, where the loop core was about 10 inches from where the knot work was started.

The bar is about a 1/2 inch thick when viewed from the side, still flexible, but probably overly substantial for most folks, to be made and worn as a paracord bracelet.

I also finished with a lanyard knot/diamond knot/boatswain's whistle knot, tied by pairing off the four working strands at the loop attachment end. With a clip on one end and loop on the other, the lanyard can have a belt run through the loop end with an item at the clip end, or clipped to a belt loop and having an item attached on the loop end.
I ended up using about seven feet of black paracord and around nine feet of the olive drab in the finished lanyard.
I used a leftover four foot length of paracord to tie a '
Spring sinnet', another tie from JD(TIAT), used as a pocket knife fob for the
Wenger S13. I started with a loop and lanyard knot then tied the sinnet, tucking the end back up into the knot with hemostats to finish.

And I made a spool knit neck lanyard with about 36 feet of olive drab 'Type I' paracord/accessory/dummy cord, with a glow-in-the-dark Gaucho knot, and another smaller three pass Gaucho tied with white 0.9mm cord on the black powder coated snap hook.
