Revision 16 is live. I updated the Wicked Edge values to those currently provided, despite the lack of explanation, as the old page has been removed.

I do not believe so. The “old” values were posted before the effect-measurement method* was discussed, and the “new” values are described with “This chart is not our suggested sharpening progression, it is simply showing the order of grits from coarsest to finest.”

The micron ratings therein are very different from those provided previously/elsewhere, e.g. https://support.wickededgeusa.com/portal/en/kb/articles/grit-comparison-table

That looks expensive. You must be quite a perfectionist to not just use his 4″ stones. https://www.cgsw.us/1×4%20Resin%20Bond%20Diamond%20Stones.html

If the shears will be used for slide cutting, whether fabric or hair, you may want a polished edge.

Any news on this front?

Are you certain this isn’t surface dirt, like residue from packaging tape?

The chart has been updated to revision 10. I would appreciate feedback on the background style change. ISP problems persist; please try a hard reload (Shift+F5) if you get a 403 Forbidden error.

To avoid a possible misunderstanding I did not perform any testing or measurement myself. I am merely using the values that Clay provided. The old/original 1500 was previously listed as 5µ in the Wicked Edge grit table. Thank you for your testing however!

What’s the knife on the far right?

Marc, that’s quite a collection.

“The Feather Super Pro has a 10 degree bevel with a 19 degree microbevel (these measurements are plus or minus 1 degree).”

These are included angles as measured by Todd Simpson on https://scienceofsharp.com/2014/05/28/a-comparison-of-several-manufactured-blades/

Mr.Wizard replied to the topic What is the grain size in Micron of the 1500, 2200 and 3000 Diamond Stones? in the forum Abrasives 5 years ago

I used these new optical image values in revision 9 of my grit chart. The original 1500 was apparently at least as fine as the 3000 stone, which agrees with the 5 micron value I had for it before. See the thread Organic linked above.
