I think Im understanding. The cell rot you just dont know untill you get a straight edge and do some testing of the strength.on the metal. And i can see about changing a razor by an 1/8 or more would change the angoe of the bevel. Thats just math of angles. But if only changing lets say.1/16 shouldnt change the angle too much would it?

Like i say, im just trying to learn and understand. I like to learn as much as possible before atempting things.
