Long time ago, doing research on stones, there were several sites in praise of Kitayama, giving great final edge and wonderful kasumi for a synthetic. However I see almost nothing on this forum. Any thoughts, experience and comparisons? To other synthetics, to naturals, to hybrids like JNS 6000? I have since gone into naturals, and this is mostly academic interest, but still curious with a nagging sense that I'd like to try it.
