Got the Arkansas stone in today, it was a lot lighter in color than I had expected. At first I thought it felt a bit course for a finishing stone. I went and lapped, and lapped and lapped it some more with 320 grit w/d sand paper till the grid lines were gone.. Now even at this lower grit she's about as smooth as any stone I've held in my hands. Tomorrow I'll do some more lapping with 400 and 600 grit.
BTW, this is a Black Translucent 8x3x1.
Here's what she looks like so far.
