First of all, COOL PIC!! Do UWO just let you scan whatever you like? would love one of those! Second, where is the difference in the 2 pics? I don't see any convexity, all I see is that it looks like the edge has become more fragile with pieces hanging off? I do find Crox harsh after a while though. If I use it more than twice to touch up I feel like it is not as buttery smooth as it usually is, it still stays sharp though no doubt. Maybe it is because my razors are honed on a coticule though I don't know.
