I've used Zebra brand ball point pens for years and a new compact model came out last year that fits neatly on a keyring, making it a good choice for EDC(Every Day Carry). I thought I'd try adding a round crown sinnet with paracord over the metal barrel.
I added a split ring, removed the pocket clip(carefully bent it back and forth until it snapped off), and then started a round sinnet with two 42 inch long pieces of paracord, leaving the inner strands intact.
I trimmed off the excess cord and melted the ends. I'll have to see how it holds with my keys and other gadgets, I think I may add a dab of superglue to make sure it doesn't want to slide off the barrel. I may try another one with the inner strands removed.
