Blue Paper Steel performance

[leeramundo]

I couldn't find much information on how Blue Paper steel performs in comparison to more familiar steels like VG10, 440, 1095, D2, S30V, etc. Usually it is only compared to the related White Paper steel. Anyone have any info on this? I understand that there are 3 types, Blue #2, Blue #1, and Super Blue. Info on any of these would be great.

Super Blue makes for a superior slicer IIRC.

Re Spyderco: Aogami Super Blue is produced by Hitachi Metals at their plant in the Shimane Prefecture, Japan. During the manufacturing process, the foundry uses high quality iron-sand found exclusively in this region of Japan to create different grades of steels, including what they term white steels and blue steels. White and blue don’t refer to the actual color of the steel but rather to the color of paper the raw steel comes wrapped in when it is delivered. A common practice with Japanese steels, for convenience and clarity, is to name and refer to steel types based on the color of their packaging. Super Blue is the highest grade Aogami blue steel and contains up to 1.5% carbon to enhance its long-lasting wearability and chrome to elevate its hardness and corrosion resistance.

Aogami Super Blue steel is produced exclusively by Hitachi Metals for tools and knives. In Hitachi's plant in the Shimane Prefecture, Japan, they use high quality iron-sand found only in this region. Shimane Prefecture sand has been used and preferred for making Japanese cutlery since ancient times. Hitachi creates and offers different grades of steels including white steels and blue steels. The steel isn't blue or white but the designation refers to the color of the paper the raw steel is wrapped in when delivered to Hitachi. It is common practice for Japanese steels to be named and referred to; based on what colored packaging the raw steel arrives to the maker. Super Blue is the highest grade blue steel and contains up to 1-1/2% carbon for wear resistance and chrome to elevate hardness and improve edge holding and corrosion resistance. Steel smiths agree Super Blue is easier to heat-treat and work with than some steels but is more wear resistant and harder to hand grind. Classified as exotic steel by cutlery standards, it has a loyal following with custom kitchen knifemakers looking for superior cutting performance for cutting materials that are soft and sticky to rock hard or fibrous.
