I might add that the CH12K is a nice choice for those folk
like me that like to touch up a razor once a week. Because
it cuts slow you can pull it out once a week and give the
razor ten strokes rinse, strop and put it up for tomorrow.
Normally once a week is too often but a slow hone can adjust
the rules.
I like my Naniwa 12K SuperStone.... a lot, if you have
room in the budget consider it.
