The one I like best is the Martelli Ergonomic Cutter, it's easier on the hands/arms and I have better control on my cutting. I have the Gingher, Olfa & Fiskars in all sizes and I used then for different projects. You will need a larger one to cut several layers, a med size for up to 4 layers and a small one on curves. When cutting several layers, I find the fabric wants to move, so either iron it together before cutting or use temp. fabric spray. This will help. Also, get a fillet glove(for fish) at the sporting or hardware store. I have also seen them at some quilt shops under a different name. That will save stitches in your finger.
