I was hoping it was real obvious that I was kidding, but I'm also a little annoyed by the people that want to depress the lock and then flip their arms around to get the blade to come out. Using the thumb hole is so much more efficient.
I've watched the videos and I can't get the middle finger to work. I have no problem flicking out the blade using the tip of my thumb, something like shooting marbles I suppose. It feels more natural to me that way and allows me to maintain a better grip on the knife at the same time.
