Executive summary: 12C27 won in this case, which perhaps surprisingly was a case where edge holding was important.
It began when I wanted to remove the diamond patterning on the handle of my F1. The CPM-440V knife was an obvious candidate for that, as the cutting involved slicing through lots of tough material (I took just a little at a time, as I didn't want to cut away to a lower level than the rest of the handle).After that, the knife was totally dull and wouldn't slice paper cleanly and the like, something it'd done very well before.
Last week I wanted to give my Fällkniven S1 the same treatment (as I've started to use it more). I thought it would be a good idea to use my EKA Nordic W11, as I wanted to dull it in order to see how it resharpens. (Yes, it's got a longer edge than the CPM-440V knife, but about in proportion to the S1's larger handle.) To my surprise, it wasn't dulled to any noticable degree.
To have been truly scientific, I should of course have done one side of each handle with each knife and at the same time so that practice couldn't have improved my technique. But I don't think that'd done much of a difference. Maybe I should also have had the edges ground to the same angle, but perhaps not, since they were about the same subjective sharpness [as in slicing paper cleanly and force required to cut strings].
Hypothesis: For this[?] material, steel hardness is what makes a difference.
