Ironically, I think Norton sells their Hard Arkansas as 2k or 4k... They make it seem like their 8k whetstone is finer... which is pretty hilarious.This is gospel!
- A Dan's Hard Black Arkansas is a 12K.
- A Norton Hard Translucent is a 16K.
- A Hark Black Translucent (like my Double Convex Ark from Superior Shave) is a 15K.Absolutely. It's 100% made up and might be totally unreliable exactly like all the other rating systems, or, maybe, it could be right. Your guess is as good as anyone's.
Worse, there's nothing we can do about it. The wonder is how well we manage to do anyway.
