To answer your question about the magnets, I've always had 2x 25mm rare earth magnets tape to the side of the trough since the beginning. But after years of use, the side of the wheel is dull and does not cut. It is interesting that they recommend the side of the wheel to flatten chisels and plane blades, but do not mention how to maintain it after some use. We'll see. The dressing wheel is one option.
