From what I know, oxide layers on stainless steel are thicker compared to that on non-stainless, but I haven't got enough data yet.
We are too early into the subject to say anything conclusive.
For now, out of practical necessity rather than firm data, we draw demarcation between the oxidation and metal memory at the 20 BESS decline, and <= 20 is attributed to the oxidation alone.
Because the high-end knife owners are so demanding, having sharpened their knives I let them rest on a shelf overnight, and send back home only when the BESS decline in 10-12 hours is < 20-30 BESS.
Timing sure matters: by BESS readings, oxidation on s/s reveals in full in 2 hours after sharpening; while metal memory events we've seen coming to maximum in 10 hours (8 hours was not always enough)...
Well, we liked to think that the first 2 hours are more specific for oxidation.
But now Mike points to one more metal memory specific time of the first 30 min, obviously Mike likes to muddy the waters.
We are learning to distinguish between the three:
- oxidation;
- the edge apex metal memory;
- the foil/wire burr, which is often considered a structural element of the apex.
I hope the new edge-rolling tester can help with this.
