Ohio's law is sorta kind written like that, but it leaves EMTs out of the picture. I'd think from knowing them all that Fire & EMS have WAY more of a use for an auto knife than any of the LEO's that I know. The big advantage to an auto Stryker over a manual Stryker is that the auto can be opened and closed with gloves. Sure, LEO's wear gloves when it's cold out, but EMT's and FFs wear them every day. For me, if I were wearing fire gloves, it'd either be an auto with a huge button or a fixed blade. EMTs wearing rubber gloves could probably work a Spyderco style blade, or one with a huge thumbstud, but it would be murder on gloves. An auto button would be a lot easier to use. Although most retail locations say that auto knives are for LEO purchase only, most every FF&EMT I know has one somehow.
