There are multiples of the Kajihara and Kanehiro, so I'm going to link the one's I think you're thinking about:http://www.chefknivestogo.com/tska21gy.htmlhttp://www.chefknivestogo.com/kawa21.html
If those aren't correct, the following could be worthless.
Of those four......Takeda.
I wouldn't shy away from any, though. 1, 2 & 4 are all incredible knives. 3 I don't recall ever seeing in person. But, it looks like a clone of Kikuichi Ginsanko I loved dearly. If it is, it's a fabulous knife as well.
Takeda, for me at least, holds something magical. It might not necessarily perform better....but it definitely won't perform worse and I really like his knives.
