Scott,
I'm trying to get a good cross section of blades in, so I've been going through my razors.
I've done Genco's, Solingen, Puma,(which is basically Solingen) Henckels, and I have a Sheffield up next. All hollow's. I've done quite a few, no wedge's though. I'm curious to see how it does on hard Sheffield steel. I have a lot of confidence in this hone though. He sent me 3 stones to test, and so far, I'm pretty impressed with just this one hone.
I also have two other hones that I believe would make excellent pre polisher's, or perhaps finisher's in their own right.
A lot more testing to do, but so far it looks very promising.
Rich
