Just learned the technique last night. Already did a b@stardized version for axis-locked folders and large lockbacks, but the official version, from the man himself, flung my ATR open lightning quick and it was tight and secure in my hand. Used to monkey-grip the clip, push the bar back, and flick it open, but Brownie0486's method was safer and quicker (I've dropped my poor ATR the other way).
The Brownie Pop, whether you end up using it or not, is a must-know.
