I agree that the second edge-leading image is odd. Clearly a big burr (you know, about 4 microns or something 🙂 ) was formed. I’m not sure why since I used very light strokes. I’ll have to wait until tomorrow to repeat it and redo the photography.
This interests me, but I can’t tell what’s going on in the 2nd edge leading photo, other than the metal being pushed you referenced. I don’t see a defined bevel like the edge trailing photo, it looks like a serious burr or that the edge is folded over, and it looks like the pic was taken farther away?
Sorry if its just me… but can you interpret it a bit?
