Not sure you´re looking for 240mm,210mm etc. but this shop in germany has a 210mm KU with the same profile (by the looks): mazaki-white-2-nashiji-gyuto-210-mm
You could send it on to the handle maker afterwards?
Although I'd wait first until you experienced whether iron cladding is something you actually want in a knife. I think at least 1 of your recent purchases has it.
