Maybe not everyones test, but that razor sure seemed to 'slide' through the paper. I noticed he made a few more passes on the stone, and sliced again. Didn't seem to be any big damage to the edge, more than a few more passes on the stone.
I'll try to refrain from calling anyone stupid, if you might do the same.
So where in Italy are these stones mined?
Since no one responded to my question, I've since done a little searching to find out that it comes from the Imperia region of northeast Italy.
After watching this vid, i think, my razors are more sharp after 1k stones, when i watch him "shaving" his arm. 2 Stone honing works with any stone i own (that is fine enough), even with a black Arkansas, just needs a "little" more time.
Using paper for sharpening tests, even makes kitchenknifes a little dull, after many attempts. For razors it is just stupid, and can instantly destroy the edge, depending on the used paper.
I got nothing to say to the Imperia Roccia hone, never tryed.
Thanks. I'm curious about it now as it is alleged to come from Italy. There was that beautiful brown Thurigian stone with rubber on the 'Bay that was sold two-three years ago which came from northern Italy (signed attestation by the Milanese seller), and the Italians who chimed in about it didn't seem to know about that one either. On the Shave Den forum, "Imperia la Roccia" (the member's name) said that it was from the Imperia region. Maybe he's one of the members here, and can clarify things further?
That must be Bushdoctor, from Il Rasoio, who lives in Imperia. From what I could make out, he wasn't familiar with a stone from his area and supposed that either it was a repackaged Taiwanese stone or that there was someone in his area there with a cave containing homogeneous slate like the one being sold. He was going to make inquiries but doesn't seem to have followed up, at least on Il Rasoio.
Edit: I just found one of his posts on SRP, where he denies that they come from Imperia, not without criticism from one member there.
