When I use my Naniwa stone progression or even my JNats I can run my thumb pad over the blade and it really sticks. When I look at the edge under a 40 magnifier the edge looks even and smooth. When I shave with it I find it a little harsh. If I go back and do 5-10 laps on my Escher under running water and try the thumb test my finger doesn't stick and in fact if doesn't feel sharp at all. Under the glass is is very polished. The shave is smooth, no tug or irritation. I also try the arm hair test and it cuts hair easily with or without the Escher. Just curious to see if others have had the same results.
