I love my Shape Cut. I have the one that is 12" wide and has the slits at 1/2" intervals. That way, you can cut any size strips, not just 2-1/2" wide. There is also a Shape Cut that is 18" wide with slits at 1/2" intervals.
My JoAnn's has the 12" wide. I just Googled it and Amazon.com has them at very good prices.
