Ok, Will give it a shot, but I don't explane things well.
I simply grip the closed blade at the tallest spot (just above the nail nick) and flick the body downwards. The knife will open to lock, and then I just kine of flip it back up into my hand.
Like I said, it takes a little pratice. And if you feel like its a miss, let it go and get your feet and hands out of the way. Do it on soft ground incase you drop it. When I close it one handed, I grip the handle with butt up and depress the lock and bearly move the blade against my thigh, then clear my fingers and take it on to close.
A lot of folks will disagree with this, but I have been doing it with my two dot almost ever since I bought it new. It is still a tight blade and my opening method hasn't harmed it any. Nor have I ever been cut. I do have small hands/fingers so that hay help me grip it easier.
And for what its worth, I can do the same thing with a Swamp Rat, Rat Trap. Not that I need to.
I did retire the two dot this year after grabbing a couple a three Alaskans with the S30V.
