Thread: Same edge, same spot, same magnification, different light...

Yes, it's an edge with a secondary bevel. I've been experimenting with it quite a bit lately. I think it's great for comparing the capabilities of various hones, because the very edge is only formed by the last hone in the progression. (There's lot to be said about this topic, but a bit besides the scope of this thread)

That was my point exactly. The angle of the light hitting the subject makes tremendous difference, even within very few degrees of variation. All pictures are lit by the same light source, only with slightly different angles. The razor itself was not touched. Magnification is 50X, by the way.

For those who wonder, the scratches running in opposite directions on the second picture, are actually very shallow strop marks.
