Cowry-X(Daido) - Kitchen Knife Steel FAQ - Latest super duper PM steel. Ultra high carbon and chromium content. C - 3% and Cr - 20%. Very high hardness, several makers harden it to 65 or even 67HRC. As you can guess very expensive too. ZDP-189 and MC-66 are very similar, in that those two have the same C and CR content. Exact element makeup unknown. Overall, very good edge holding and toughness. Hard to sharpen compared to other steels, nothing impossible though. So far Hattori is the only one making kitchen knives out of it.
