I was recently talking to Willie Klaja, about how I gave him the idea to do an opposed bar in a hexagon shape since I couldn't get one to work myself. As much as I hate step cuts, that was the only way I managed to do one myself. Works in materials from quartz to CZ (RI = 1.54 - 2.16) with no changes, but I prefer it in quartz. Suggested size = 6-15 mm
