Well I think that I'd go with a SAK for sure, they are much more "tool like" and not looked upon as "weapons". I wouldn't go to expensive on the fixed blade knife, just in case you loose it. When in the cities keep it in your backpack with the rest of your cooking/eating stuff. That may help. Laws here (USA)vary from state to state and city to city. PM me if you need any Califorinia information.
