Both were tied with short two-strand wall knot sinnets, each using less than a couple of feet worth of paracord, ends trimmed and melted in place with a wood burning tool.
I put several aspirin in the delrin pull, and a folded up bill of cash fit in the brass one. That's a $1 bill, lol, need to save up for something larger to go in there.
I had a four foot long strand of paracord leftover from the twenty foot length that I used on the bat light grip in the previous blog post. I used it to tie a chain sinnet as a keyring fob, adding one of the pewter Aquilo Sugar Skull beads that Schmuckatelli Co. sent me a few months ago, finishing with a lanyard knot.
