Versus acute edges, I'm guessing obtuse edges require greater precision at all stages in the sharpening protocol, for similar reasons as why obtuse edges have poorer edge retention ... but that's just speculation on my part.
What are the best BESS scores folks have achieved for highly obtuse apex angles?
a shot in the eye - we discussed this with Youngbin (SHARPCO), as we've noticed it is way easier to get a razor sharp edge under 100 BESS on a knife sharpened at 10 dps as compared to 20 dps, and also attribute this to a greater precision required in grinding and honing because it is easier to round an obtuse edge.
As to the 30 dps blades - out of curiosity, it is not about knives, is it?
