3 knives that i own really stand out. 1st a third Gen 550, I just touch the thumb stud and the blade flys out on it's own! 2nd a Reate D9 Tanto, same thing, seems like the blades all recoiled up waiting to jump out! 3rd A Carson Tech Boiling, the perfect amount of detent, bearing smoothness, and blade length. You can't get it to screw up if you try!
