It's amazing to me that these issues have to be litigated at all, much less that they take years to resolve. Here's 14 pages from the California Supreme Court declaring that a Swiss Army knife, in the open position, is not "locked" and thus not a "dirk or dagger". California's (likely) next U.S. Senator, current California Attorney General Kamala Harris (also of Peruta/Richards, etc. fame) argued, essentially, that ANY knife (including all folding knives) is a "locking" knife, and therefore the legislature was stupid when they made a distinction in the law between "locking" knives and "non-locking" knives, as there are no "non-locking" knives. The California Supreme Court disagreed with her. Enjoy your Swiss Army knife! Even if a blade is open and in your pocket you are now no longer a criminal in California.

Here is a background article from a year ago regarding the case.
