I have one of these. Don't need it. I feel like a SpecOps Frogman every time I use it. Would recommend.

It's also illegal to use this to stab people. There's lots of illegal ways to use lots of things

Them reviews don't look too happy... unless ya really need the serrated edge, you can get a Morakniv with belt sheath for same price and don't gotta worry about the blade snapping in half.

I'd rather get caught carrying a knife and argue it's a tool not a weapon when it literally says tool and is marketed as a tool, made by a tool company.

It is 100% legal in every state if carried as and used as a tool. A hammer stops being a hammer (legally) the second you use it to assault someone. Doesn't mean they are considered deadly weapons in my toolbox.

Good thing I live in NH. We can carry whatever knife we want, even switchblades, as long as you are not a felon.
Live Free Or Die, it's not just our state motto.

If you're a felon and work HVAC in NH you have to use safety scissors, or you just can't have a switchblade?

Most state's have a maxium size 5.5" (that's what she said) but it is completely different if it is conceled. That is usually around 3-4".
