Well none of us has, or will have first hand knowledge of whether convex hones were used say 100 years ago. However, there is obvious visual proof that some razor manufacturers use them contemporaneously. There is also the prominent Dovo reseller, who has been to Solingen, talked to grinders, manufacturers and is claiming that they have been used this way for a long time. Maybe that isn't proof, I never explicitly said it was, hence to quote my previous self, "It does seem..." Given the availible information, would it not? The only reason it would be the opposite, is if the source of this claim is egregiously lying. I have no reason to think that, maybe you do? As far as my own research into honing razors, I have never come across much that specifically mentioned the shape of the hone, but where it was referred to in a tangential manner it seem that the hone was prescribed to be flat. Now maybe if I could read German, and I acquired some old grinding and honing literature from 19th century Solingen, convex hones would be described therein. But I can't read German, so rely on information that is relayed by third parties who seem 'in the know'. Maybe that is wrong, but we can't know everything first hand.
