Reviewed Erasteel website again, found ASP2009 Steel missing from the steel chart, added. FOund another good source for British tool steel names from various companies, added about 100 more names form there. Strange, but up until now I never found a British still manufacturing company making tool steels. The only one I had before was a dealer and another was making just stainless steel, AISI 440C steel being the best...

About a dozen new GOST names, and fixed a few alloy status flags for other records.

One more pass through the Crucible catalog, and found two more alloys missing from the database, CPM Rex 86 high speed steel and CPM Rex 66 high speed steel. Added a few more GOST standard names as well.

One more Miyabi knife landed with me, with the really messed up edge too. Resharpened, used it for couple weeks, get some impressions, do considerable amount of cutting. It's a good one, if you are ok with Miyabi handles, and are not necessarily looking for exotic steels, then VG-10 will server you well. Detailed review, including testing results and some comparisons with the Wusthof Grand Prix paring knife are posted on the site.

Thanks again to Shinichi Watanabe, who provided compositions and explanatory info for the Shirogami 1A, Shirogami 1B, Shirogami 2A, Shirogami 2B, Aogami 1A, Aogami 1B, Aogami 2A and Aogami 2B steels.

Found another new source, added bunch of new names for Romanian STAS, German DIN and W-Nr standards. Fixed few more grouping errors as well.

Went through Latrobe, Crucible and Diehl steel listings, again. Well, I do that periodically to keep up with their new alloys. Nothing super existing, I did find a new one, sort of, Latrobe now lists CPM 20CV steel, which is identical in composition with Duratech 20CV steel, and interestingly no longer listed on Latrobe site, while CPM 20CV is not listed on Crucible site.

AISI 420 steel One of the oldest and mostwidel used steels in the knives and I had the composition off... I suspect it was messed up back when the database didn't support alloy groups with multiple compositions. Well, it's all good now, according to AISI specs.

Several fixes in the database. Added Latrobe Lescowear tool steel composition. Merged Vascowear, Z-Wear, Cru-Wear and Lescowear with Latrobe LSS-PGK and Lohman PGK steel group. They're way too similar to be in differnt groups. Thanks BF's Mastiff for pointing that out.
