I have a 210 Ginga and 150 Kono HD petty. Have not had a 210 Kono HD to directly compare to my Ginga. I would imagine though that they are very similar, both are considered lasers, thin behind the edge, and a fairly flat profile. My Kono petty is highly asymmetric though, for that reason you might consider the Ginga, unless you are a much better sharpener than I (which wouldn't take much).
