Sarge, we used to think about that a lot, back in the days Bill published Rockwell testing results with his files on the DOD's.
Kesar used to come in at 57, 58, ; while Bura was always 59 or 60 or even a tad higher. I thought Kesar was making his khuks for the real world where real people had to work. (and it was Yvsa back then who pointed out that 57 is a lot easier to sharpen but still a good working edge) But everyone wanted 'hard', and the Kesar's weren't quite as desirable, for that and other reasons. (Bura had the elegant form)
