I started with a knife. I'm not a fan of the butterfly because it's over-hyped for a crappy blade. By the time you're done trying to scare me with the circus flip show, I'll already have buried my Gaitor in your chest. And that saw side isn't going to be nice when I withdraw it.
They're fantastic blades. Extremely durable, very sharp, and agile. Next, the flipping is not a scare tactic. It shows how dynamic the blade is. How many ways can you unsheathe a knife or a sword?
For more info, watch The Transporter 2 (in the opening Jason Statham kicks ass with one) or The Punisher (some dumbass tried to take Frank Castle with one. Frank takes it, flips it and bashes his face in with it. Little known fact, Butterfly knife is even dangerous sheathed).
However, I'm a fan of all blades, so don't think I'm hating on your gaitor.
