I never knew we were obsessive about them, thanks. Only ever owned the one staedtler (mars). We call them clutch pencils in oz. And my Dad used it for maybe twenty years before me. For anyone else who wants to know, the big difference between the 2mm clutch and the smaller leads is the clutch maintains the direction of the lead so you can sharpen it much finer - below 0.1mm. At the same time you can use the side of the pencil for a much thicker line.
