There is a tremendous amount of hype in the cutlery industry as pushes are made for steels which causes a lot of misinformation to be thrown around as fact. However in this case the promoted advantages of D2 over SR101 are reality. D2 is a steel highly optomized for light use blades, it allows a high hardness and has a very high wear resistance with a decent ability to resist surface corrosion. Note as well that unlike most Jennifer was quick to point out the disadvantage of D2 which is that is isn't suitable for heavy choppers or prybars, this frankness there could definately be more of.
