One handed opening is available in so many non-switchblade forms.
Assisted openers are legal just about everywhere in the US as are the spyderco's and hole in the blade types.
I can open mine just as fast as an MC-1 or other automatic.
I wonder why the military still persist with automatics ?
It's a shame that the "Switchblade" has such an unfounded bad rap.
Purely psychological, automatics are no more effective than any other folder as far as a weapon is concerned.
It does help in an emergency, one handed opening no mater what type.
Guess the 1950's did it. Funny now a hoodlum would be embarrassed to pull out such a thing.
