Added alternative name Sandvik 20C for the 1095 steel. Fixed 1095 steel composition accordingly, as Sandvik had better and more precise specification sheet. Expanded descriptions for the rest of the Sandvik steels.

The new comers are both from Carpenter Technology Corporation. Micro-Melt T15 and Micro-Melt T15 Plus. Both are high alloy, high wear resistance tool steels. Here's T15 vs. T15 Plus steels chemical composition comparison.

For one, 52100 steel was not listing SR-101 in the a.k.a column, so added that. Second, S7 steel was listing SR-101 as an alternate name, which was incorrect, Busse Scrap yard knives use modified S7 steel, but label it as SR-77. Fixed that as well. Streange so many Busse/Swamp Rat/Scrap Yard fans never caught on that :)

That was the last weekend, three knives sharpened. Easiest, and biggest was the lonaer, Shun chukabocho or a Chinese cleaver. 60-61HRC, and even if cleavers aren't that easy to sharpen free hand, due to their sheer size it was still faster than the other two knives at 64HRC. Well, it'll dull that much faster too. For the record other two knives were rehardened BM 710 M2 and Phil Wilson CPM 3V utility scalpel.

Finally the mysterious Carbon V is in :) Although, as I have learned it was Wayne Goddard that analyzed the steel and published its composition in his book The Wonder Of Knifemaking. Composition - Carbon V steel.

Fixed a bug when url encoded query string containing name search pattern with spaces wasn't parsed properly. Added general query counter. Well, finally started working on Watanabe Mirohsi Deba review, should be up in next few days.

After adding today's search improvement I overdid with security checks and correct queries with numeric input stopped working :) Now it's ok.

During one of the revises noticed those two are the same, just different standard names. Fixed. I guess we'll have quite a few consolidations in the coming months, as I revise data and get more accurate international names and specs.

From now on, spaces and dashes in the steel name search pattern will be treated in a specific way. Considering that the same steel is referred with all the variations using those two symbols, e.g. O1, O 1, O-1 are all the same steel. Therefore, each pattern is analyzed for the presence of those two symbols and if they are present second pattern is generated, which has all the spaces and dashes removed. Thus, the search for O-2 will return O2. If you don't want this behavior, and want strict matching, simply enclose pattern in double quotes. "O-2" will search strictly for that pattern.

Yet another Aichi stainless steel.
