I'm curious about the MinoSharp wheel systems - more accurately, I have one, but I'm curious about it's relative effectiveness compared to an actual stone. They are somewhat curious in how they apply the techniques in this course. Both in how they achieve it, and in that I now know how much is going on when you push the blade through the wheel. First, as the wheels spin on the blade, I imagine they make a motion more akin to pushing it over a stone than dragging across a V-shape, as it typical with hand-held gadgets. Second, the wheels are angled horizontally, as well as beveled vertically. This seems to keep the edge away from direct contact with the bottom, allowing it to be ground from the sides. But I'm not sure if the angle that it contacts the wheel matters at all. Being a rounded surface, it only makes contact with the highest point. Third, the wheels do both sides at once, so I imagine no discernible burr should appear on either side, but how does this relate to the stropping techniques? Do you need to strop an edge with no burr? Fourth, they are ceramic wheels. Chad covers ceramic only in reference to steels, but doesn't go into detail on how well they'd work as the primary abrasive - is there any reason to think it wouldn't be a good abrasive surface? -Aaron
