What specifically does "Opens Automatically" mean, with respect to a spring assist?
"Assisted open" knives are legal since they require the user to exert pressure on the blade itself to engage the spring assist.
Switchblades open by applying pressure to a release button and not the blade.
It is a small, and stupid, difference.
The idiocy over switchblades came about when I was a kid and movies of the day purported that switchblade knives were the primary weapon of "Gang" members.
Which was a huge load of crap.
The true stupidity is that sheath knives are perfectly legal and they require NO opening assist of any kind.
Just draw it from the sheath and cut away.
Yeah.Yeah, but the Sharks and the Jets don't look as cool when they pull their sheath knives off their belts to have their dance fight.
