All right guys, I've got pretty good results converting a spike to a spanishish/barber notch. but I want to take a round to a spike (and maybe beyond). but with the round there are two problems I see going in:

1. more material to work with
2. how to keep it straight?!

I'd love to hear your guys experience and ideas. I also have an idea I thought I'd pass on. Sadly taking it to the belt grinder is out, too much heat TOO fast. (but man, it'd be a perfect flat edge).

so this was the only thing I could think of. I have a small 1" wide belt sander somewhere under the big workbench. I was thinking with water trickle (if I can work it out) or without. take a block of wood, route a groove for the edge to lay in, clamp that to the table and then lay the razor in there, thus keeping the belt running in the direction of the edge.

thoughts? grit to use? (I'm not even sure what's available for small sanders) I wish now I had set my belt grinder up to be variable speed. I can get really fine grit belts in 2"x72".
