Do any of you use an Escher after a Naniwa SS 12K?
All I can say is give it a try. The grit rating of both stones are pretty close to one another but they put an entirely different edge (feel) on a razor.
Yeah, my thoughts are, hone the razor up to the SS 12K. Then finish the razor with an Escher to give the edge that nice natural stone finish.
Matt, I do not own an Escher and cannot give any comment on it. But this idea of honing up to the SS 12K with a synthetic progression and finishing on a natural stone was given to me by Alfredo (Doc). I did hone my TI 6/8 "Fox and Rooster" last time by using a Chosera 1K and Super Stones 5K - 8K - 12K. After the SS 12K I did 50 light laps on a Coticule wet with a few drops of mineral oil. Results were fantastic, with a very smooth edge. Hence, give it a try and let us know!
12K naniwa can cause chips in the edge if you don't stop on time. Make sure you know how to stop on the naniwa before going to the Escher or the Escher will not make the edge feel nice.
Escher is a final stone, use it last.
Congrats, Matt!
I find the biggest feel on the face is the final stone.
There are minor and very subtle differences in the feel of a full nagura progression on a razor vs just a tomo finish. Very small but perceivable differences.
If your doing a 12k after an 8K synthetic I would say probably 20 would be near the limit and I would use a Thuringian after a 12K or even after the 8k and skip the 12k altogether. A few more additional laps after the 8K with the Thuringian and you would have an edge just as keen and smooth.
You are correct it is based on the stone and the razor as well. Some razors will take more strokes and some less. If the edge has been taken to the best level that stone has to offer in 20 laps the only thing you will accomplish in 50 laps is the possibility that you make a poor stroke and have to start all over but the edge will not benefit anymore.This of course also varies by the skill level of the user.
