Here is a link to the White #2 JKI Gesshin Ginga 240 gyuto. These Ashi Hamano knives have great fit & finish. But its only available in wa handle.
Here is a 240mm yo handle, only available in their swedish stainless, similar to the Kono HH I suppose. Really nice grind, fit and finish on these too. Also made entirely by Ashi Hamano for JKI.
I've had both and preferred the semi-stainless TKC over the stainless Ginga. I think the Ginga was slighter better finished (polished and rounded spine and choil), but the TKC has a great distal taper and that semi-stainless steel takes a better edge and feels so smooth on the stones. Are you willing to try a wa handle?
