I picked up a new Norton 4k/8k a week ago and I haven't honed
anything with it yet, but I thought I'd give it a quick lapping with
the flattening stone today.
Wow! It didn't seem to cut that evenly when I got started on the
4k side, and took a few minutes to get rid of the grid on certain
spots on the stone. The 8k side was far better, but I'm sure it's a
good idea to take the time to ensure a good flat surface even on
a brand new stone.
What do you guys think?
