With a little oil and working the blade a while, I can grasp the blade of a 110 or a 560 at the peak with thumb on the nail nick and flip it open with one hand. Then a slight flip up and either one falls neatly into my hand. My Dad fusses at me some about doing that, but doesn't take much pratice to do it without getting cut up. Just remember that if the move doesn't feel right, let it drop to the ground. Duh!!! And in effect your hand is going down and the blade is going up. That is if you do it right!
Sure, this isn't near as smooth as one handing this 277 Alpha, but if it keeps the cost down on the 110, I am happy.
But a custom 560 or 110 with smoother opening would be interesting. Has anyone had this washer thing done?
