Expanding geographic coverage of my knife steel composition database. Found a good source, at least most of the popular knife steels, as in tool steels, high speed steels and plain carbon steels are covered. Working on obtaining additional data. That particular source is depleted...

Found more detailed composition and fixed incomplete data in the database. one of the confusing steels, this is not Hitachi White 2 steel, but Takefu White 2, lesser quality Carbon steel compared to Hitachi Shirogamis.

Added Takefu V2C steel composition. Used by Masamoto in their Virgin Carbon steel kitchen knives series. Appanrently this is the cleaner version another alloy, Takefu V2 steel. Less Cr and impurities like P and S.

Thanks to Rottman from FF, again! he's the one who provided Aritsugu A-Type Gokinko steel composition. This time, he dug up SC145 alloy, made by Lohman for German knifemaker Achim Wertz. SC145 steel is an ultra pure alloy, cleaner than famous for their cleannes Hitachi Shirogami and Aogami series. 1.45% Carbon, and just 0.004% and 0.003% S and P.

Compared the composition of the AISI S1 tool steel against SAE J438b standard code, found considerable discrepancies, one of the oldes entries in the database. Fixed according to standard code. While at it, checked the rest of the S series shock resistant tool steels in the database. S5 tool steel composition was also off slightly, fixed that one too.

Fixed AISI L6 steel and AISI L7 steel compositions according to SAE J438b standard code. For L6 steel added corresponding footnotes from standard code regarding Mn content and presence of Mo and V in the alloy, apparently those two are optional.

I've known about Takefu COS-3 steel a little over a year. Finally I got the composition :) From Spyderco forums. Used in Spyderco mule for now.
