EDGE RETENTION/ROLLING PART II

[subwoofer]

Those are some excellent results and great efforts for valuable findings.

Just to double check, was the original intent of this test to see if the process of sharpening changed the properties of the steel at the edge, making it behave differently to the rest of the blade steel? (and therefore potentially casting doubt over the validity of the results from the SET)

Of course careless sharpening will cause issues, but as long as the sharpening process does not introduce heat treat issues or work harden the edge, then it would seem these early results are suggesting that the SET results are indeed valid for directly checking the performance of the steel. One variable removed.
