OK, this is what I came up with. Remember, this is how I understand the law. From what I've found, I can own a double edged knife, "dirk or dagger", but can only carry it as "open carry". This is where one would have to be very careful, as concealment is determined by the officer. I would imagine the only place they would not have a problem with it being carried, is if it were duct taped directly onto the forehead. Actually, I'm kinda happy I looked into this, it was my understanding that I couldn't possess one at all.

One thing in Cali that is for sure a no no, is a cane sword. I always thought these were somewhat of a novelty, a joke of sorts. Till I watched a couple videos put out by Cold Steel on the one they offer. Wow, is the only word to describe it. Since a leg break darn near two years ago, followed by a total ankle replacement in November, I've come to accept that I'll be using a cane for the remainder of my life. I don't know how criminals think, but I would imagine if they see a wounded, limping person with a cane, they would assume me to be easy prey. I've put in for a CCW, but I really like the cane sword idea.
