I'm new to this forum. I'm 15, I live in California, I have a question though. I'm taking a trip to Yosemite very soon, and I would like to know if anyone has info on fixed blade carry in National Parks. I'd like to take a Ka-Bar combat knife with me on the trip. To be honest, I'm not even sure that it's legal for a minor to be carrying a blade that large? I'd probably openly carry it on my backpack so it wasn't illegal concealing of a weapon, but I'd like to be assured that it's legal for someone my age to carry a medium fixed blade knife into a National Park. If I couldn't take the Ka-Bar, would an SOG SEAL pup be a better option?
