If your making your own lanyard, you can use the break-away buckles from a cat collar. I have used a few of these with paracord bracelets and neck lanyards. Check the craft section of your local Walmart,they have break-away necklace clasps. I used 1 long piece of mason twine tripled back on itself, then braided.
