Gerber Shard is an inexpensive EDC key chain tool, featuring a prybar, nail puller, wire stripper, screwdrivers, bottle opener, and lanyard hole.
I tied a 7 lead 6 bight turk's head knot, three passes, with about 4 feet of 0.9mm nylon cord for a little extra decorative grip around the center of the tool.
With another Shard, I tied two Spanish Rink Knots, doubled with 0.9mm cord. And another with a Gaucho knot, tied with 2mm cord. The last is shown with a three pass Gaucho knot with black 0.9mm cord.
