This thread is teetering... Pick your knife, get a clear kydex belt sheath. Maybe consider hanging a Victorinox off your keys with a carabiner. Moving wouldn't be a bad idea ofter 7 years and all. People are trying to help, but with so many conditions, exceptions, "oh and's", it's pretty damn hard to help. I would think it is fair to say the people participating are every bit as frustrated as you are, maybe even more so. Also, last time I checked, a belt sheath for a knife is not considered clothing, then again the folks in Richmond might be on "another level".
See and the way I read "open carry" for a folder, a tucked in shirt with the knife clipped inside the pocket would suffice... even with only a little bit of knife sticking out it's pretty easy to see what it is. But it sounds like Richmond folks all carry them clipped outside the pocket. I tried it once. Can't imagine seeing it every day as the regular mode of carry.
