    What is the difference between...

    ... An automatic knife and a spring assisted opening knife?

    I recently purchased a S&W M&P spring assisted opening knife. For those unfamiliar with what that is, basically I press a button and the blade pops out instantly. However, in my home state, automatic knives are still illegal for everyone except military and police. So I'm wondering if somehow this could get me in trouble.

    So what is it that makes this knife legal and the automatic illegal where I live? It seems to me there's no difference. On both, I merely push a button and the blade is released. How are they different?

    In an assisted opening knife you actually have to start the blade, or physically touch it and give it a nudge, to get it to open. Once it gets past a certain point the spring takes over. Automatic knives have a release and the blade will come out all on its own without touching it at all.

    That's just it, I don't physically touch the blade to open it. I press a release nub and the blade pops out. In all fairness, I could use the thumbstuds to open it, but they're so small it's uncomfortable to open that way.

    Here's a link to the one I bought:

    Even on their description, they say it's more of an automatic.

    In FL, with a CCW permit...no difference!
    In many other states...BIG difference.

    IMO, is an automatic just because you have that option, besides the assisted opening option. I would not take a chance carrying it if illegal in your state.

    I have the MP5LS, and it's officially considered to be an assisted knife. The release nub is part of the blade. The button is on the spine that pushes directly against the blade. Even Smith & Wesson market it as an assisted knife.

    In most states, the MAGIC-assisted knives are the closest one can get to legally carrying an automatic. Though here in FL, like retsupt99 said, it doesn't matter for CCW holders.

    I watched a youtube vid on the knife and I kind of figured that nub was attached to the blade, but it sure looked like it didn't need much effort to get the blade to pop open using that nub, hence the safety. It makes it seem like an auto, even though technically it isn't. I wouldn't want to be arguing that point though.
