I have woodland camo as well as silver, but I'm seriously thinking of picking up some digital desert camo duct tape. It'd match my SHTF bag and my boonie hat, lol. I'd love to see a digital desert camo duct tape tuxedo, lol.
My Recon Tanto came with a crappy sheath that was falling apart. A real sheath for it costs about $50, and the knife was free, so I wasn't about to drop that much on one. I found a new sheath at a flea market for $5 that was about 4" too long.
I cut the excess off and rebuilt the end of it with several layers of camo duct tape (now it only has about 3/4" of slack in the end) and then covered the sheath with camo duct tape. I'm thinking the digital desert would go a lot better if I end up in a situation of carrying it on the outside of my SHTF bag.
