I find myself looking to add a small (2-4") fixed-blade knife to my daily carry, but I can't seem to find any manufacturers who sell a knife with a discrete sheath intended to actually use. The typical injection-molded sheaths I can find (CRKT, Cold Steel, etc) appear to be designed to sell with the knife, not to survive daily use. Can you recommend a couple manufacturers I should look at who take sheaths as seriously as Blade-Tech, Comp-Tac, or Safariland take kydex holsters? Most specifically I'd like a 2-3" knife, with a real handle, in a discrete IWB sheath, on the left side. . . . or maybe I should (gasp) look at a lefty automatic.
