Ok, that last post concerned me. For someone who never sharpened, and has a Persistence and has a Delica coming, Sharpmaker or get stones, like a Norton 220/1000?
You shouldn't have any problems using the Sharpmaker. Among many examples of my knvies, I've resharpened my VG-10 Delica's plain edge very easily and an AUS-8 combo-edge Endura; also my PE Salt 1 and Pacific Salt, I was able to resharpen with virtually no effort using the Sharpmaker as well. I also resharpened an Emerson CQC7-A; although the Emerson's single-sided edge bevel did not match the angles of the Sharpmaker, I simply put the edge against the rod, noted the edge angle, and adjusted the angle at which I held the knife accordingly.
I've sometimes wondered if some of the ATS-55 had been heat-treated imperfectly or something. I'd resharpened other ATS-55 knives okay, but some of them seemed a bit more difficult for me than most other steels, even hitting the exact same edge angle. I don't know why, but reading Tomsch's post, it looks like I'm not the only one who's experienced it with an ATS-55 blade.
I mean, getting stones is a good thing, but IMO, if you have never sharpened, the Sharpmaker is a great tool. Even then, you'll get better the more you use it. Because I had never sharpened before owning the Sharpmaker, either. I had the older version, then upgraded to the 204 eight or more years ago.
