What to do when the wet stone gets carved out a bit.
After some time my DDF IohEF Stone was no where near flat. Looking online I thought I needed something like this special flattening stone to fix the problem.
But after reading this article I learned sand paper can also work. So I gave that a try.
They recommended 220-grit sandpaper but since I didn’t have any on hand I did 40, 80, 120 grit in sequence.
I took quite some time but in the end worked great!
