Last year I mentioned to my DH that I had seen a Fiskars ruler and rotary cutter used on an online fabric shop. Since I have periodic bouts of my carpal tunnel come back to haunt me, the thing that appealed to me was just having to push down and not hold the rotary cutter. To my surprise he ordered it for me, and I was thrilled, as it truly is easier to use than a ruler and separate rotary cutter; although I do use those as well, but it really saves my wrists when I have a lot of strip cutting to do.
