Got a set of Shapton 4K/8K/16K glass stones this week. I also got an Atoma 1200 for lapping. Now, my Henckels-Friodur 7/8 full hollow was due for a refresh (or so I thought). So I lapped the Shaptons and went to work on the razor.

I did twenty strokes on the 4K, ten on the 8K, and five on the 16K. Followed up with 80 strokes on linen, 40 on leather. I then did my normal pre-shave routine, but when I put the blade to my face it was completely dull.

Where did I go wrong, and what can I do to bring back the edge?
