I used to use the Martelli rotary cutter til my hands got too bad. Did love it though but it just isn't an option anymore. Darn it.
However, several of us have the cutting mats. It seems like our rotary blades don't get dull as fast ... really and truly.
If you know of any quilting expo type show nearby Martelli will probably be there. Am curious why they won't ship to Canada. Good luck.
