I am posting some better pictures of my "Dragon Slayer" The blade is 210MM on the edge and about 225MM including the bolster The ferrule appears to be buffalo horn, the handle is D shaped, probably HO wood. Many thanks McKemaus for the help. The blade appears to be stainless, I like the finish. Comments are welcome.
I just heard from the person I bought this knife from that she bought it from Korin. I checked, they no longer sell it. It has a Kasumi finish. According to Korin the steel is either Ao-Ko, Shiro-Ko, or Ginsan-Ko The seller said the knife came highly recommended by Korin as a entry level sushi knife It is single bevel, for a right handed person. I posted better pictures if anybody wants to chime in.
I took McKemaus advice and contacted Mari at Korin. She said Korin has never sold it, and she checked with others at Korin, NADA So I am back to square one. My best guess is this is a entry level stainless yanigiba. I now have a cheap beater to practice my single bevel sharpening on. Case closed, thanks everyone for your help.
