Edge Retention/Rolling Test Stand

[EOU]

Excellent thoughts subwoofer. You're not alone in your advocacy. We're all entering an area where no man has set foot before. We're all devil's advocates at this point. I can assure you, we have no agenda here and few theories. At this point, the only thing that we can tell you for certain is that we simply don't know. We hope that your speculation is correct, that we are testing edge hardness and/or durability because that is where the rubber meets the road in most applications. In fact, if your speculation is not correct then we are likely wasting our time here. 

We hope that there is a general correlation between hardness and edge durability (as this early test seems to indicate) because that doesn't rock the boat of conventional wisdom. We've rocked the boat before and it's no fun.  Assuming higher hardness steels roll less than softer steels then we get to explore all the other contributing factors like all the edge geometry issues, sharpening technique/methods etc.  Just quantifying the edge rolling characteristics of HRC 60 vs. HRC 62 is going to be interesting though. Then there are various steels that might both have identical hardness characteristics but do they resist rolling to different degrees? More combinations and permutations here than you can shake a stick at.

Our general goals with this device are simply this; to help separate reality from myth and to elevate speculation to a set of evidence based findings. That's the bottom line and thank you very much for your comments and participation here.
