For you knifemakers out there. what is the best and consistant way to grind the edge to a knife that has a bit of curvature to it.

all i can tell you is have a steady and consistant hand. use a grinding wheel and hold the knife at a 45 to 30 degree angle downward with the blade facing upward and grind slowly across the length, keeping the blade about 1 cm on both sides of the portion being grinded, perpendicular to the grinding wheel. move the blade in the motion to sharpen a few times across the grinding wheel before turning it on to get a good feel for it, and hold on tight! i suggest making a piece of curved stock metal to practice on.

Do you want to just sharpen it or are you making one?

ya, my comment was based on making an edge rather than sharpening one. if u wanna sharpen one, just get a stone kit.

On the knife making forums I go on the blade makers use a slack belt sander to shape the blades.

If the knife has been tempered, you risk ruining the heat treatment by grinding it. When I was blade smithing we used two belt-sanders. One with varying sized wheels for profiling and one with a flat plane for working the edge.
