Thread: Norton 8k = ~5k JIS?

The really important thing to remember is that grit size is not the only factor that affects how fast or how deeply a hone cuts into steel. This is the reason Lynn said that you will have to give it a try. These tables don't tell the whole story. The binder, the grit density, and the grit friability also come into play.

The young honer says to the old honer;
"Hey old man, lets run down the hill and hone on that 5K!"

The old honer responds;
"How about we walk down the hill and hone on them all."
