This law, that law, bah. Fact is explaining to detectives how you successfully defended yourself with your kerambit (or flashy OTF, or bali, or big ol fixed blade, or CCC stainless sword with "Ninja Master" etched on) are all pretty much the same thing. You now have to explain why you were not only "accidentally prepared" but "gung ho and looking for trouble". The cops barely expect anyone with a CCW to be proficient, now here's Tommy Flashblade trying to explain how they used martial arts and took down the assailant with their carry kerambit? Get something you can reasonably explain, like : "I use this 3" fixed blade to open boxes at work". I think you'll find that a lot less problematic when the chips fall where they may. Razel styles in pocket sheaths are great choices for that, plausibility where it counts. The guy who posted the wharnie had 100% the right idea.
