I recently ordered a couple of Gerber Shards which arrived in the mail today, and have already tied a red and black gaucho knot on one of them with 0.9mm cord. The red looked a little faded after working and tightening the knot, so I touched it up with a red Sharpie marker to deepen the color.
Here'a a link to a blog post from a few years ago with some past knot work done on a few Gerber Shards. I kept one and it gets rotated with the edc keychain setup and some of my other prybar type tools, like the Leatherman Brewzer.
I've given several to friends and family for Christmas and birthday gifts as they are mostly inexpensive as multitools go, durable, and a handy piece of kit to have around.
And another Shard shown with a gaucho knot tied with some 1.8mm orange reflective line that I'd bought on ebay a while back and hadn't used on any projects yet. The cord has a reflective tracer thread running through the outer sheath of the cord. Type I paracord might also be used for a wrap on the Shard, but I find the finished knot a bit thicker than I prefer, but some folks might not mind it.
I'm an Amazon affiliate, so 'Thank You!' to those that shop there through my links, since I receive a small commission from sales through those links posted in my blog.
If you need an edc backpack, check out the limited edition VENOM and VENOM RED mochi drawstring backpacks with Stormdrane logo, which I receive a percentage of sales from, each having a stitched paracord handle that I worked with Mochibrand on for the design.
