I have 3 Delica's (and some other similar Spydercos, both plain and serrated), with my oldest Delica having been purchased in 1991. I've carried one nearly every day since and have no trouble opening it as fast as any auto with either hand. It often rides clipped to my left pocket when there's a Doubletap .45 in my right. I wouldn't want to mess things up with a 'snag' feature. I don't see the need. But to each their own.
