Work is being super busy... Can't get much time to do anything, including weekends :( Added few more JIS and DIN names today, whatever I managed in small breaks. If I get this weekend off, I sure hope to finish knife steel chart for android, or move closer to the finish considerably.

AISI T4 high speed tool steel had incorrect DIN standard name, fixed that, and added Russian GOST standard name. Added few other DIN and W-Nr names as well. At the moment, chart has 2900 names, closing on 3K mark rapidly. Bad part is, I don't get any serious time to finish android steel chart 2.0 :(

A little data form the history. Mushet Steel was the first ever official tool steel, invented by Robert Forester Mushet. Experiments with it led to the development of high speed tool steels later on. This is a grand father of modern tool and high speed tool steels, and as such, it definitely deserves being in the knife steel database, even though nobody uses or produces it in its original composition.

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.
