I'm looking at an ad for Smith and Wesson "Auto Opening Knives."
Aren't these just switchblades, and if so illegal?
It depends on your individual state laws. In some states autos are legal, in some they are not.

Get a SOG assissted opening instead if you are planning on buying
a knife. I have owned a few S&W knives and they
just didnt hold up if used not sure about their auto knives though.
Most experts will tell you a regular opening knife or the assissted opening
knife opens just as fast if not faster than the autos. Just lacks the coolness

It seems like so many of these states just copy a lot of this law from a template. So many places that knuckles are illegal. like just flat illegal. I cant believe that anyone put any thought into making that decision when open carry is not only legal but you dont even need a license ( I support open carry and cant wait till we win the fight in Texas)

Would having a concealed carry permit change what you can have?
In Missouri you cannot carry an automatic/switchblade (unless you're a LEO) regardless of whether or not you have a CCW .

Assisted openers, etc. as well as fixed-blades are fine.

That said, you don't want a S&W knife anyway...

Yes, know your state laws!

For example, in Florida, my CCP allows me to carry any concealed weapon. Even though this license is good in many other states, most of them only allow me to carry pistol, even though my license says 'concealed weapon or firearm license." State laws trump when I travel.

In Florida, I can carry a legal sized shotgun under my coat if I wanted to, five pistols and auto load knives. Once I leave here, need to just carry the pistol. And I need to be sure the state I travel to does not outlaw my weapon or magazine capacity.

And, get a Gerber. :)
