The graph now can display alloy compositions in three different modes, as element mass %, as atom count and as molar mass %. If you are unfamiliar with Molar mass, you can look up the details on wikipedia, but it's actually quite simple, the same number of the atoms for any element has the mass in grams of the element atomic mass, except the number is real big :) 6.0221415 E23. It's real interesting to look at atom counts and molar mass, because mass % doesn't really show the whole picture to analyze the steel.

I couldn't find suitable tester here in SF bay myself, but one of the foodies, Rotman sent his A-Type to test in Germany. Test results should be in about 2 weeks from now. Current popular guesses are Lohman PGK steel, Bohler-Uddeholm K340 steel, VascoWear. Well, I figure Latrobe LSS PGK steel might be a good candidate as well, since it's almost a duplicate of the Lohmann PGK.

Added about ten new alloy compositions from Lohmann, German steel maker. Most noteable is PGK steel. Plus over 50 names for other alloys already in the steel composition chart.

Half a dozen new aliases for the AISI T15 high speed tungsten tool steel.

Monday, everybody's favorite day. So, I am chasing Crucible and Latrobe reps to get the damn permissions on the charts. One doesn't pickup the phone or return voice mails, the other doesn't reply to emails. And that's the stuff they publish and want to distribute...

And another 10K... Unrelated, but no answer from Crucible or Latrobe about copyrighted materials.

Added more aliases for the 10xx series steels, W1, S1, D2. Too tired for more detailed report :) Cool feature upgrade in the steel composition graph builder, will do provide details tomorrow.

Minor typo, Cyrillic X was sitting in the name, instead of the Latin X. So, it is 95X5GM.

I wasn't really planing on overhauling the review, but first I got several questions why did I assume the blade was X50CrMoV15 stainless steel and why did I think it'd be 54-56HRC. It's more or less easy guess for any knifenut familiar with the western kitchen knives, but I know not everyone is a knifenut. Second, I finally found Gude official website and updated the review with a few details from there as well. Well, I hope now it answers all of the questions.

After redirecting me to another person Latrobe remains mum... So, I'l start sending emails again next week. Interesting, what's so bad about geting their published(!) data.
