AEB-L/13C26 has an INCREDIBLY fine grain structure equal or finer to most of the PM steels (some call it "stainless 52100"), no vanadium, molybdenum or tungsten to speak of that I know of and a medium carbon content (60%, about the same as 5160) and it is very good WHEN HEAT TREATED PROPERLY. What it may not have is the abrasion resistance of some of the high alloy steels, but it is one of the go to steels for the customs kitchen knife guys who expect the kind of sharp edge on a knife that most of us would never dream of.
