One more overhaul, this time it was a large one. Added general description, usage section and more importantly separate section discussing the use of the diamond stones and tapes for the ceramic knives. They're not designed to be used on normal steel. Quite detailed explanation of the nature of diamond stones and their behavior is in the review, special thanks to ben Dale, owner and the founder of the Edge-Pro Inc.

More tool steel goodies form Hitachi. First one, HAP72 PM high speed tool steel, as far as I understand, patented too. next, XVC5 tool steel, which is a JIS SKH57 variation from Hitachi. And finally, one more Hitachi patented, SLD8 tool steel. Added bonus, because I stumbled on them while researching SLD8 steel, few more proprietary and one standard, GB(China) standard names for the good old D3 tool steel.

I'm attempting to get additional data from Crucible and Latrobe at the moment do add to the knife steel composition chart, well individual steel records. They both have charts, diagrams, etc comparing steel properties. Sadly it is a really slow process and chances are I have to get permission for individual graphs. That's gonna be real pain.

Trying to find out ZDP-189 and Aritsugu gokikno steel compositions. Finding a lab to test steel composition in bay area proved to be unexpectedly difficult. Still, managed to dig one up. Trying to work out the details.

As planned, conducted comparative test cutting, well, normally speaking, did some kitchen cutting with Tojiro Flash Santoku and Henckels Miyabi 7000MC Santoku. And as usual it happens with the weekend loaners, I ditn't have enough time, at least not as much as I wanted. Oh well. It still worked out pretty good :) Took photos of theedge damamge on the Miyabi santoku and Tojiro had couple chips on the blade too. Took few shots of those as well. I'm too tired today, too late too, so pix and hopefully the review updates will be up next week. Miyabi did require more serious sharpening, well, it's been almost 6 month since I've sharpened that knife. Serious enough to start with the Shapton 220 Grit glass stone. Then the usual steps, pretty much every sharpening stong listed in Synthetic sharpener reviews, excpet for the Naniwa Chosera 10000x Super Finishing waterstone. Then followed up with the usual 0.50 and 0.25 microne leather strops and a plain leather strop. Sharpened Tojiro flash santoku as well, since it was gonna be used with Miyabi. That one started on 2000-3000 grit Aoto waterstone. While I was at it, sharpened Phil Wilson's small chefs knife and touched up Watanabe Honyaki gyuto on kitayma. All in all 2 hours on sharpening, 1 hour on cutting with tojiro and miyabi santokus. Like I said, if all is good, review updates next week.

Another loaner knife reviewed. Shun's Honesuki. Main interest point - Takefu SG2 PM steel. It's a pretty solid performer, and well made knife too. However, I still prefer my Watanabe Pro Honesuki knife over Shun's. Details in the review.

After more research and help from Ben Dale(Edge-Pro Inc founder), the new, improved table is ready. Currently it has Edge-Pro grit value conversions to Japanese Waterstone grits and microns. If you have more info on that, please contact me.

As per users request, added chemical element explanation help to the graph toolbar. Now you can invoke it just like from the interactive knife steel composition chart. I'm on the roll today :)

Kigami(Yellow) saw steel. Also used in cutlery. Makeup identical to Shirogami Saw steel composition, except higher percentage of the impurities P and S. That should conclude today's Hitachi YSS steel saga.
