Tanaka Kasumi are similar to the Sekiso line except they do not have the Damascus pattern on the blade and are less money because of this. These are great values. The knives are hot forged with a core blade of Blue Paper steel (HRC 60 and up). The knives come with a traditional "D" shaped handle and buffalo horn ferrule. They also come in an attractive presentation box.
this is a no frills workhorse yanagi. good price,good quality. only downside was the handle which was a little uncomfortable.
Very nice knife for the money. I keep the knife on a towel next to my board at work(sushi bar). The blue paper steel can be pretty reactive so utmost care is needed to keep it from spotting,holds a very keen edge though,F&F is a little disappointing as far as the handle there is a tiny bit of rotational movement of the tang inside,but the blade is secure.
