Okay, so, I've realized I need a finer hone than what I've got right now. I'm not actually even sure what grits I have available to me, but none of them will hone anything up fine enough to shave with. :P

Lee Valley has a set of three diamond pastes, a 1, 3 and 6u tube. I can grab a bit of old MDF scrap from work to paste it on to, or maybe some clear pine if that's better...

So my question is two fold. What kind of commonly available construction materials could I put the paste on? (I'm trying save a buck here. :P)

Secondly, is any of those three pastes useless? Any one of them problematic? Also, does anyone know roughly what grit 3 and 6u would be roughly equal to in terms of stones?
