real bear to keep flat...

A piece of leather, rough side up, on a flat board and charged with jeweler's rouge works better for a final polish. As Stick said, slate is hard to keep flat. 

Just wondering: Would a flat piece of granite work for a final sharpening? I have access to a pc. about 12"x12". Hmmm, I might just try this. Has anyone else tried it, and if so, how does it work?

think of as a extremely hyper-fine till you get  through the polished surface... wich will take a lot of work to keep polish, clean and flattened...

also..

hardness of granite and slate isn't uniform..

as you use the stones ripples will form in the surface.. think roller coaster...

You can use the flat granite to mount sandpaper for "scary sharp" and then avoid all those problems of flatening and oiling stone.Just one of many videos on the subject.

that's gotta be the #1 use for a flat granite slab...
