My first Emerson (many, many years ago) was a CQC-11 with a Krein regrind. It was ridiculous. Today, my Shiro F95NL gets really sharp without going crazy acute. My Gayle Bradley 1 is another good one. And I can get pretty darned great working performance out of my Large Inkosi. MD/Laconico Keen also takes and edge that is quite, well, keen.
