The non-locking 3-inch blade of a Swiss Army knife is not good as a weapon. If you ever need to use a Swiss Army knife for self-defense, flip out one of the half-length, center-mount tools--like the corkscrew, Phillips-head screwdriver, or preferably the awl--and hold the body of the knife in your palm, with the tool extending between middle and ring fingers. Then punch with it, until you get an opportunity to escape. If you try to cut someone with the knife blade, you'll likely end up breaking it off or closing it on your own fingers. A knife weapon absolutely needs to have a fixed or locking blade. And that's why a police officer will never have a problem with a non-locking pocketknife. A cop might. A pig definitely will. As long as the latter exist, you might as well carry a tool-knife with a "legitimate purpose" that can also be used as a weapon-knife if necessary, because following the spirit of the law won't help you it a letter-of-the-law bastard gets it in his head to screw you over.
