Lapping Plates

[JOB15]

Last night I honed up a blade ready for a shave today. (In fact I have to test 3 razors today)

This morning I decided to re hone the blade because the HHT was not as good in the middle of the blade and there was no obvious reason for this.

Soon realised my 10k Chosera wasn't acting how it should. I normally use it then clean it with a Tomo Nagura.

I used a pencil and my DMT 325 to lap it but when I finished I thought , lets try now with the Shapton Diamond plate .

The stone was badly dished out yet the 325 was showing it as flat ..

The same story with my Escher.

I think I will only use the DMT 325 for slurry and only use the Shapton for lapping..

Just thought I'd warn you that your diamond plates or should I say worn diamond plates arnt as flat as you might think..

Or is the 325 just coarser than the Shapton? I know the my Atoma 1200 is finer than the Shapton
