I got it back for sharpening, and during the weekend I'm gonna sharpen, test against the Tojiro Flash Santoku. That's more valid comparison compared to 270mm Sanetsu ZDP-189 gyuto.

Seems like that AISI 10xx series never ends. One more alloy that is used in knives and was missing from the chart, AISI 1069 steel. One would think AISI 1070 steel is pretty much the same, but may be someone can get 1069 cheaper or something...

Man... That AISI 10xx series never end. Found out that AISI 1064 steel was also used in several knives, by several makers. Added more standard names to the following AISI 1055, AISI 1060 steels.

Two form Bohler-Uddeholm: N688 stainless steel and N692 stainless steel. Both were discontinued, but given the fact that both were used in cutlery, the knives made out of those two will still float around for a while, raising questions about their makeup.

Found more precise composition of the Arne steel from Bohler-Uddeholm. Swedish version of the AISI O1 tool steel and W-Nr number is - 1.2510.

5 new alloys from the French company called Bonpertuis. Actually, I've never heard of them, but while researching one of the Boker knives I stumbled upon T6MoV steel, and then dug up the rest of the bunch: T5Mo, T5MoV, T7Mo, and T9Mov. All are cutlery steels widely used in the Europe.
