For a long time it has remained high speed PM steel, used by Tanaka, Itou and dunno who else. On occasion the same knife would appear listed as SG2 or R2, which did gave a clue. Anyhow, now it is officially confirmed by several trustrworthy sources including Koki of JKC, and Tanaka as well. In shorrt, Kobelco steel makes R2, which is supplied ot Takefuy which sells it under SG2. You could generalize though, R2 is the name used by makers who forge it and use more complicated HT process, and SG2 is the name for factory knives, laser cut and stamped. Obviously this is purely abstract, and any maker of factory can do whatever they please.

Two more days before a new toy arrives
Well, I'll post an update once I have it :)

Fixed one more bug, when for a single alloy with more than 12 alloying elements javascript warning about insufficient space was showing up.

With the last steel chart and graph builder upgrades I've introduced a bug unfortunately. In the graph, on the image soft hyphen unicode in hex was showing up :) Removed that, but not too happy with the fix, need to work on performance some more. Never thought steel chart database would grow this big and now I have issues with performance.

Changed layout, improved graph readability, changed graph layout as well, fits more elements now, added warning with detailed info when not all alloys fit in the graph and few other upgrades. Fixed a bug when autosuggest wasn't working for alloys containing & symbol. Added javascript versioning for graph specific files, but for core js files you still need to refresh manually using SHIFT + refresh button, otherwise autosuggest will not work.

One of the visitors posted a message for me on bladeforums, pointed out a new source - Associated Steel, not much but picked up few alloys names, added to the database already. Trying to follow up with the manufacturer, they don't list the compositions, although claim alloys are improvements over the standard counterparts. Interesting how, could be composition change, or just as easy, better manufacturing process.

One dude complained in app review case steel wasn't there. I've checked, well I did have Case CV which is a short name. What I don't understand how do people search or why they don't search using dedicated search button... Type case and it pops up. Well, ok added it with full name - Monday, April 1, 2013 23:38:50
Got multiple user requests to add alloying element effects to the app. I've added that feature to the Android app about a month ago, and finally made it for the ios version as well. Same deal, in detail view and graph view tap on the elements toolbar item and then, in the popup list tap in the info icon, it'll display alloying element effects.

One of the readers brought to my attention that CCR(California Code Of Regulations) has a separate provision dealing with knives and dangerous objects on the grounds and in the buildings of the University Of California. Basically, unless you are a student, or employee or have a lawful work to do with your knife or bunch of other stuff, it's a no. As it is phrased, you can get arrested for carrying a screwdriver...

Revisions and updates were going on and in for last two weeks. Number of alloy groups were missing notes, and that was the main focus of these updates. Will continue as usual.
