Still just dipping my big toe with this hone, but experimented a bit more. It's pretty breathtaking how sharp you can get a blade on this. Very minimal number of passes seems to be the order of the day. It's going to take me awhile to learn how to get the most from it. I am honestly surprised that this is so different to the purple lune. Purple has a lot of cutting power and a good piece can get you past a thuri by a touch and still be comfortable, this romps past a thuri in the sharp department, but what you get seems more highly strung. I will work on that.
