I went to the Atlanta sewing and quilt expo this year, planning on getting the Martelli ergo rotary cutter. My DH went with me this year. While watching the demo, he said, 'You really ought to get the whole set.' I really needed a new mat, and the ruler they had was amazing. He bought me the whole set! Cutter, mat, ruler, and 5 extra blades. The cutter is better than any other new one I have had! So much better for my wrist!
