I've noticed that a lot of the alloys for knife blades that have good edge retention are from PM (often, but not exclusively, sintered). I always assumed it was because of the types of alloys they could make, but this article suggests that the uniformity attainable through PM might be a bigger effect.

Yeah, I was wondering about the particle metallurgy process (or the equivalent from other foundries). I know that AEB-L and similar Sandvik steels are ingot steels. Would the added cost be worth it? What about something LC200N (Cronidur 30)? Great corrosion resistance and toughness. Comments here talk about corrosion leading to micro fractures. Not sure if traditional toughness in terms of cutlery applies here.
