Thats pretty neat!
I suspect the reason why some peoples edges hold for longer periods (2 months or longer) and some for a shorter period is most times directly related to whether or not you use some pressure when you strop! I've always used pressure when stropping and then lightened the pressure some with the finishing strokes. I usually get 3 to 4 months out of a razor before it is neccessary to touch it up, and many of my razors get more time than that before touch up! I usually strop 30 to 40 times on leather though. maybe I should do less stropping and see if I get longer lasting edges?
