Are you absolutely committed to the idea of always wearing a belt under your clothing and tying a knife to it? ... even on a retractor system? I wonder if the risks and complications outweigh the possible benefit(s). I certainly don't like the idea for any self defense purposes. Perhaps loss-prevention in a survival situation... but anything you tie to yourself ought to "break away" under reasonable stress anyway: imagine the things you can be hanged from or anchored to in a survival situation if your knife/gear lanyard was too strong!
By the way: are the two small holes in the grips of the Stryder AR lanyard holes? They look kind of small for paracord. I didn't see any other lanyard holes when I looked at this knife on their web site.
