Well, I was comparting to/with something like Durit's GD20N [0], which scores 1400 HV30 which should be like 83.6 HRC or thereabouts.
It's a WC-Ni powder metallurgic composite with 9% binder. Their website suggests that they make blades for industrial paper cutters, but I'd assume those use normal WC-Co due to paper not being particularly corrosive.
Sure, the geometry matters a lot, but that's also fairly orthogonal from the metallurgy.
