There must be some sort of line that is drawn when fast drawing becomes dangerously fast drawing. Since it takes a little while to get used to opening a new knife, I spent a little time with my 710sbt and have come up with the optimum level of power on the part of my wrist to get the blade open just enough, no more and no less. The opening feels exactly like it would if I was literally guiding the blade along with the thumb stud, only MUCH faster. If the knife smacks against the stop pin and slams back down, you are doing it too hard. Since the stop piece on the handle is plastic, I am not as worried about the blade smacking into it, but I still think it's an issue of wearing out a knife and its mechanism before its time. I have never had an Axis-Lock before, I don't know how long it is going to last. Unlike most knives, if you open the 710 too fast you KNOW IT. Oh hell yes you know it, the entire knife vibrates, its a large piece of steel hitting the stop pin, you can can tell if you need to modify opening power applied from your hand.
