I have narrow my choices down to the Carbonext 210mm and the Miyabi 7000mc. The Miyabi 7000mc look pretty decent from what it is. Has anyone have any experience with the ZDP-189 powder steel. It promises to retain the edges very well, but would not maintain an insane sharpness and will stay at a decent sharpness for a long time. I would be sharpening it with only a 6000 grits stone. Thanks once again.
