I see in the HI descriptions of various blades a number for Rockwell C hardness, and noticed that they often seem quite high for such large blades. Also, given the pictures I've seen of the factory, I just wonder if the kamis test hardness there with an instrument, or maybe calibrated files, or whether that's done in Reno. And is it done for every blade or just spotchecked from time to time. I'm just curious.
