Dumb question: im fresh out of sandpaper to lap my 4/8. An emery board (like the ones you use to clean your nails up, but this one is absurdly aggressive haha) was sitting on the counter.

Could I have used it to lap the stone? It really wouldn't be fully lapping it, more like a refreshing between lappings. Haha

If I'm an idiot say it! :-)
