So my dad has an old "Sabatier 4 star" 240mm chefs that has a beautiful Arc de Triomphe in the middle after years of careless pull through sharpening. I'm visiting this weekend and wanted to have a go at repeofiling it. The steel is the normal Western stainless I'm guessing some kind of CroMoVa15. I don't know the HRC but I think it's safe to assume something in the 58 range. BecauW I'm flying i don't want to bring all my stones, and I was planning to bring a Shapton Pro 320 and a 1k/4k combo or a Chosera 1.5k. Unfortunately I don't have pictures of the knife, but if you put it flat on a board you see the light through the arch. Will these stones be enough? I won't have several hours to spend, unfortunately, so only want to do this if I have a reasonable chance of success within the time frame. Otherwise I'll take it back with me and fix it in due time.
