My edc knife is a case xx as are most of my back up edc knives. They are all about as fast I can pull the blade out....can't think of a time I've ever felt a need to rush it any.
My EDC / Fastest knife is a Benchmade Osborne. I can hold it by the scales and make a minor counterclockwise motion to flick it open faster than any other knife I own. They are usually powder coated a flat black, but it was looking bad, so I ground it off and steel wooled it...
Gotta love knifes... My wife is all - "How many knifes do you need?" and I'm Like "Shut up and make me a Sandwich."
Was messing around with a few and actually looks like my Mini Barrage might be just as fast! I have seen the Emerson Wave and opened correctly, those things fly out!
