Sorry if you meant CANADA.
Noah,
I believe Dave lives in Canada.
No problem with khuks, swords, or other long knives in CA. State law does not have a length limitation. However, beware that the Communists in some municipalities and schools have laws limiting length and other features that are only obeyed by the law abiding anyway.
As far a airline travel, I've never had a problem with knives in the checked in luggage. Sometimes the TSA lookiloos want to open the bag because it looks strange to them in the x-ray.
Also, technically as far as state law is concerned you can wear a khuk or sword in open carry. However, I wouldn't do it in the city as you would scare someone and attract law enforcement attention unnecessarily.
