I've added paracord over some of the ball chain necklaces, used other pendants on EDC key chain setups, and have tried a few different knot work ideas with some, including the long 4 bight Turk's head knot tied over this one.
0.9mm cord knot is a bit too loose for my liking without some way of better securing it to the underlying navy blue paracord covered ball chain, like maybe added a bit of strategic needle and thread work along the length of it.
I had intended to do a Gaucho knot over the ends, covering both ends of the Turk's head knot and where the paracord comes together over the ball chain clasp, but not interfere with it being able to safely break-away should the necklace ever get caught on something.
I could tie a tighter pattern with more leads or make more passes, but I'll probably just untie this one and try some hitching ideas.
You could certainly wear one as shown, just as long as you don't go trekking through briars and brambles where it could snag and pull the knot work all out of sorts.
And another one shown with two Gaucho knots tied with 0.9mm cord, on each side of the split ring attachment on the pendant. The pendants come with a jump ring, but I swapped them out for slightly larger split rings.
