I have the 28mm & 60mm and 2 or 3 45mm. The one I use all the time is the one that the blade cover automatically closes when you release the handle. It really spoils me for going back to the straight handle cutter that I have to REMEMBER to engage/disengage the blade each time I pick it up/lay it down.
