Reply To: Edge Finishing
A few questions if I may:
- What is the 90-90-90 rule ?
- What is the autosol step ?
- In the three-step approach, “1 degree more obtuse” would start a micro bevel I think yet I suppose this is to address the burr root ?
- In the three-step approach, “0.1 micron … at the original sharpening angle” is quite a jump from 1.5 micron ?
- Also, I wonder if this is all necessary because after raising (edge-trailing) the hanging burr at 100, 200 diamond grit; then all the rest of the diamond grits I do edge-leading through 1000, 1500, 2200, 3000. Then edge-trailing with 3 grits of diamond film and finally 2 leather strops each with finer poly diamonds. It would seem to me that the burr root should be addressed by this but maybe not. I guess the proof would be in controlled BESS testing (maybe I will get one).
I am mostly interested in the concept of extending the longevity of a very sharp edge. I also wonder how the Tormek wheel geometry compares to the flat WEPS paddles in his approach. I need to read Verhoeven’s Experiments in Knife Sharpening again.
