I had a white steel Korin Yanagi,used it alot.Came in a Suisin box,so I figured it was made by them.I bought mine almost 8 yrs. ago.I don't see it on their site now,it was a little more expensive than the Shiro-Ko.Even back then paid over 200.00 for a 270mm.Cut alot of fish wt. that blade.164.00 for a Korin 270mm I think you did fine.
