Hey Guys,

Can someone explain to me how a lower grit stone can create a higher polish than something more than 2x its fineness? From what I know about sharpness and scratch pattern refinement, it seems so antithetical. Specifically I see this occurring from Naniwa 2k Green Brick to the Rika 5k. I just want to understand what's happening on the microscopic level when I make that jump.

Thanks.

It's how the stone works. A stone like the Naniwa green brick does not release its abrasive with most sharpenings, collecting the metal on the surface of the stone which has a burnishing effect to the edge giving it that glossy shine. Compare that to a Rika which is a muddy stone and the released abrasive moving on the surface creates a different effect, a hazy dull look lacking the high luster. These are the two main working styles of stones, polishers or muddy.

It has to do with now the abrasive cuts. Think of it like this--if you sand wood to 120 grit with a belt sander, you will see scratches. If you sand it to 80 grit with a random orbital sander, you won't see any.

The odd thing is JNats--they will put a hair-snapping, grabby 12k edge on a knife that is as hazy as San Francisco.
