Thread: Does a Suehiro 20k need to be lapped?

Here is mine, gotten over a year or more ago, and I lapped it immediately. As you see, the corner is still not lapped. At the first go round I called it 'good' when I knew I had enough real estate to hone a razor. Figuring as time went on I'd eventually get through that corner with the lapping plate.

Many, many sessions of lapping/honing later, it is what it is. If I live long enough maybe the whole thing will be uniformly flat one day, but no sense wasting stone, when there is enough to use, just to say "it's flat" ........
