Got alloy data files form the Ahonest Changjiang steel company, and I'm adding the data as I go through it. That's the company behind many steels used by Spyderco, Benchmade, CRKT and few other makers. Takes time to match their records to existing groups :) Added 2Cr14Mo steel composition, added few more aliases and names to various alloy groups, and fixed 9Cr13MoVCo steel composition and added one more alias for it.

One of the knives we gave as a gift to our friend, to introduce him to Japanese kitchen knives. I was happy to have anew knife for testing and reviewing, me and my friends were happy to pick a worthy present and recipient was happy to get the knife he wanted. Everyone was happy in the end, including the dealer I suppose :) Anyhow, good knife, solid build, solid performance. I have no clue why would Tojiro conceal Takefu VG-10 steel used in this knife under obscure DP name, but that's how it was for a while. Details in the review.

Added notes to few dozen alloys. Fixed Carpenter CRB-7 steel composition. Added precise data for Carpenter CTS-B70P steel composition.

My biggest toy in recent years, if not ever :) And it is my first EV to boot. Very geeky car IMHO and I love pretty much everything about it. Smooth ride, tons of gadgets, huge touch screen, very high acceleration and regenerative breaking which is far more important and convenient that it might seem just by reading the description, I can drive that car using one pedal 98% of the time. No more gas station visits either. What can I say, truly 21st century car and I'm glad I have it.

One more knife donated by maker for testing and reviewing. Because of its rather unusual features the knife went through the very rigorous testing by me and was loaned to several of my friends, who are not knife collectors, but I was interested in their input just as much. The highlight was Crucible CPM S35VN steel which in this knife is hardened at 60-61HRC and exhibited excellent durability and resistance to edge damage in average user's hand. Other than that, it is quite unusual knife, at least for me, used to Japanese kitchen knives, but for details there's a real long review linked above.

Found a link on the KKF, listed bunch of the French steels used in knives, and to my surprise, some of them were not in the database. THen dug around some more, and found few others as well. In short, about 20 new alloy names were added. To name a few - XC-130 and 135Cr3

One more loaner, had it a while back for some time. I suppose you could call it a yanaagiba for a westerners, who are used to different knives, although that kindda defies the purpose of the yanagiba. Well, looks cool, performs much worse than it looks and in short this is the knife that shouldn't be. Still, apparently someone wanted it and Miyabi made it. The rest in the review.

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.

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