I've had a couple of ATS-34, and still have a couple of S30V, that need a diamond plate for bevel set, and a synthetic progression to get shave ready. At least at my house that is what they need. YMMV.
Old barber (70) cutting hair for 50 years, Frank Natale. Told me in 1980s that he liked a soft coticule that he could score with his thumb nail. So of course I've tried this with every coticule I've ever had. There is just something about coticules. If I wrote a book about them it would be the 'romance' of the coticule.
