Whoooaa, Agent 22!
I believe Mr. Mattis was comparing the fixed blade "bird and trout" with the FOLDING version of the A-F (with a "sharpened" double edge). If I'm reading you right, you might have thought that he was talking about one of the FIXED blade A-F versions, and thus guessing that laws might be more relaxed concerning fixed double edge blades.
I doubt that, since most of the State Codes I read about almost always mention "dirks and daggers" by name when enumerating illegal knives.
Maybe I read you wrong, though, and in fact I may be wrong about CA open carry. On the other hand, even if open carry of straight blades is legal, if someone is frightened by your display of bladery, that someone might call the police and the they might get you on something else, ie. "disturbing the sheep," or "inducing hoplophobia."
Anyway, welcome to Bladeforums! Either wait for someone else to comment or let us know for sure what Applegate-Fairbairn variant you thought Mr. Mattis was referring to.
And pardon my
! I just don't want to see someone get snookered after misinterpreting the law. By the way, when I was about your age, I carried my Gerber Mk. I while mowing the lawn around the Bonanza restaurant where I worked. It was for cutting weeds, of course. But that was 1979! Times have changed. I wouldn't carry a sizable fixed blade in Ohio, unless it was in the woods.
I hope you don't mind my asking why you want to carry a fixed blade?
