I definitely second the "Oland tool" approach. I was fumbling around trying to deal with small details as well. Stumbled over Darrell's site and built my first tool using 1/4" HSS toolbit from Enco. I have since ground over half-dozen profiles - on both ends of the toolbit.
I do the rough grind on the 80grit grinding wheel, then finish up on the belt-sander. Finally, I do a quick hone on a bench-stone. As I use the tool, I just hone on the stone to maintain an edge.
Also, I've been playing with cutting profiles using the small grinding stones you can get for the Dremel and other hand-held grinders. It's slow going as the stones don't hold up well to HSS but you can get some interesting results.
