    Although AEB-L is not a powder metallurgy steel, it contains very tiny carbides, its average carbide size is six-tenths of one micron, powder metallurgy steels have a carbide size of 2-4 microns. This gives AEB-L excellent toughness, great ease of sharpening, ease in grinding and polishing, great wear resistance, and a very keen edge to a knife.
