I just got my Spyderco Tri-angle Sharpmaker 204 and have been practicing with some of my cheap knives. I'm not sure though if I should be using it on my Global knife or not.
1. I read that the factory angle for Global knives is about 15 degrees and the edge is convex. With the Sharpmaker it seems I should be using the 30 degree rod setting to achieve the 15 degree angle. Is this right?
2. In all of the pictures in the manual the knives have a straight edge. Is it ok to use the Sharpmaker on the convex edge of my Global knife or will that ruin the edge?
Any other tips or suggestions?
