Any auto in CA is a no-no....![]()
My understanding is an auto with a blade length of less than two inches is legal in CA. Kershaw makes one. I have one, and don't care for it much. It's to small. It's hard to hold in such a way, that you can push the button, not have a finger in the way of the opening blade, and still have enough grip on the knife, that it doesn't jump out of your hand from the opening force. I would expect a 55 auto would have similar shortcomings, but maybe to a slightly lesser degree.
O.B.
