Jan, I use an Olfa Ergonomic Rotary Cutter (yellow). I've had it for years and that is all I use for most of my cutting. I have a little Olfa 28mm cutter, which is the first one I bought back in the late 70's when I started quilting. I use it for PP. I keep it right next to my sewing machine with a 12" rotating rotary cutting mat.
