Florida carry law is a mess. Everything is considered a weapon except a "common pocketknife." When I asked two leo's, my local sheriff's office, my local PD, and the FDLE what a common pocket knife was, i got about two dozen differnt answers. Short answer is "it depends." Basically, the law is written so that the arresting officer can charge you with concealed weapon first degree misdemeanor (1 yr in prison) if he/she feels like it, or doesn't have to.
If you're moving to FL on a permanent basis the first thing you should do is get to a gun show and take the CCW class. in FLorida, it's a true concealed WEAPON permit which also applies to all cutlery (yes, to the best of my knowledge, autos are legal statewide, but individual counties and cities may have other ordinances). Basically, if you can conceal it, you can carry it. Check out Chapter 790 of the florida statutes.

Hope the link works.
So in answer to your question, if you are walking around without a ccw and you get stopped with a Sifu, I would bet good money you're gonna be in trouble. Get a ccw. Takes 90 days and all the hassles disappear. Until then, anything past an SAK is pushing it (in the opinions of the several leo's with whom I have spoken).
PS, don't let the yahoos in the knife stores, etc tell you about the "four-finger rule" regarding blade length. There is NO statute about length, etc on the books. See the link above. Hope this helps.
