LABOR <> MOWG is correct, in that, I tested Mr. Magnus's knife when it was originally fabricated. I was actually the first one to use it, even before he. It has been repaired, and is on it US tour, right now. I'm last to receive it which should be in a little over a month. I'm excited to see MR.M's design perform to its potential.
MR.M did tell me the profile was modified slightly by the regrind whereas the union of the two distinct flat spots was radiused off a bit creating a bit of a belly... if you can call it that in such a small portion of blade. Nonetheless, MR.M's radical design was, admittedly, for shits & giggles. Said radius should, in my mind, employ more usable length in a rock/glide/walk. I can't find the video I captured, but the first profile would pivot off the head of the rear flat spot so if you were walking herbs, e.g., you only had that flat spot minus the pivot point available to cut; the entire tip flat spot was never employed - cutting a 240 down to say a 200. I think MR.M's design would be more appropriate in the 260-280mm range because it was, before the regrind, truly two knives in one blade. It was peculiar as it looked/acted like a KoBocho as the tip flat spot, and then a flat profiled Gyuto as the rear flat spot. I would have liked both flat spots to be longer for them to had acted more efficiently. I didn't realize any particular benefit to the tip flat spot in chopping scenarios as I believe MR.M imagined it would, but again, he did it entirely as an experiment. I think if it was longer maybe it would have, but honestly, the knife was so unenjoyable I didn't want to use it anymore than the 2.5 days I put it through.
