No offense intended, just an observation: I see it as similar to a butterfly knife, in that your average street person thinks they're super-cool and scary, even though a basic, legal flickable folder would be open & in use in about a tenth of the time it takes to open a butterfly knife.

My usual pocketknife is a Cold Steel Hold Out.
