I'm pretty sure in CA, it's actually legal to carry an exposed pistol, provided the chamber is empty. There's some grass roots ...
I also don't really advocate a stick. But... if you're going to have one... A) cattle prod (imagine the suprise of the dog when he bites onto a live current), or B) one of those sword-in-a-stick are options to consider. I don't know the legality of either of those, however.
Open carry requires that the weapon is completely unloaded. You can carry the ammunition on your person, but not in the gun. There's a political movement (AB1934) to do away with this after a couple of idiots decided to open carry black rifles at political rallies. Either way, it's socially taboo and compounded by the fact that I'm don't particularly like guns. Longbows and traditional recurves are more my speed.
Sword canes are expressly prohibited under California law. There's a couple of densely worded paragraphs basicly stating that any knife has to look like a knife. Also batons, saps (included weighted monkeyfist knots), shuriken, and general havoc-causing-what-not are off limits.
Getting back to a tangent on the original subject. Since I don't want to drop $40 on a potential chew toy, what's a good reference for finishing up my own hardwood walking stick?
