I don't see much purpose for an assisted opening knife either. I can open my waved Endura faster than any other knife, autos included. Besides, it only takes gross motor skills - it's just a matter of puling your knife out of the pocket. Whereas with any assisted opening/auto knife you need to fiddle with a button.

Seriously, if speed is of concern, get a waved knife. As simple as that and (still) legal.
