Question: how does the law define one handed opening exactly? Does it say "can open with use of one hand", "opens with use of single hand" or "needs two hands to open"? Because, if it says either of the first 2, I think you could make a strong argument for a knife that used some other mechanism than just one hand- i.e., a waved knife, a particular sheath, etc., and thus is not a "one hand opener". Also, is the simple ABILITY or the INTENTION what makes it one hand opening? A Buck 110 would be legal, but what if I put thumbstuds on it, or found a way to manipulate it open singlehanded? Any thoughts?
Or, the other argument would be to find the definition of a sheath knife- California defines a sheath knife as a knife that is in the ready position or something, explicitly defines folding knives that are locked open as sheath knives. So, if there was some way to make a knife fold yet be declared a sheath knife, that would be the way to go.
Otherwise, what is defined as a lock on a knife? Something integral that activates on it's own, or any other type of thing? If you were to take a slip joint one hand opener, open it, and manually put a locking collar on it right there, what is it defined as- an illegal knife? Or if you break it down again, what then? What if the lock needed to be manipulated first before it locked? Would that work? If you had a knife where the lock activated after pressing a button or lock release, is it a locking knife?
Take it down to really precise reasoning. Get some German legal scholars on it. This is a time that someone like Bernard Levine, but of Deutsch nationality would really help.
