This was a bit of a paracord doodle. Experimented with a number of things, from half hitching to cover the 6 oz lead ball, my first star knot (used to introduce 4 more working strands), my first 6 strand round sinnet around an experimental core (a spring from a plumbing "snake"):
... finished with a manrope knot using all 6 strands. I then used my 4mmx4" Individual Steel Paracord Fid - Lacing Needles to feed in the two ends of a bight formed for a lanyard. I used these two strands with the 6 from the manrope to tie an 8 strand diamond knot. It's a working piece so I used scraps and some splices. Planning a video about these striking type paracord weapons. This sort of thing is for entertainment and informational purposes. I won't be carrying or selling!
