That being said, the geometry does
seem to be quite legit on this M390 Delica, without implying anything beyond that.
I'll also say that the knives I've reprofiled to <30° cut better than any factory edge regardless of BTE or spine measurements. One of my knives is a Sage 2 reprofiled to right about 30 inclusive, and it will cut better than any factory Delica, Chaparral, Dragonfly, Police, you name it.. The S30V on it feels like it was done particularly well too, so i'm sure that helps. My ZDP Dragonfly reprofiled to ~22-25°, well, that literally just flies through anything and everything, it has no equal as far as my collection is concerned.
If this M390 Delica is indeed 30° or under, I have really high hopes that it will perform as one of the best, if not the best factory blade ever produced. I have a few on the way so I guess II'll find out soon!
just got them in... I CAN confirm that these slice on par with something that has been reprofiled to around 30 inclusive. For a factory edge this is very new for me and I'm liking this direction we are going. hopefully next we will see complete regrinds.. thinner PM3, Manix, or lil Native with a 30 degree edge would be absolutely awesome! Slap funky new colors and supersteels on them and call them super-sprints. Or make it the new flash batch.
