Yes I confirm,
in my experience I did some pattern welded blades and if you reflect the light you can see a bit the different, of course, much depends on the type of steel. I noticed that when the sanding belts are new, the contrast is greater. with a P100 is already possible to see also an differential hardening.
Jurgen, a question about the abrasives, you know if the Romans used Aquisetum for polishing metals? is a plant rich in silicon which can be used to polish. If I remember correctly the Romans used this plant in medicine so maybe they knew other uses of this...but I do not know. You know it?
