I was going to say rotary cutter and ruler, but then I looked at the photo in the link of this "June cutter". I thought WOW!! Hey! That's my ruler!! I love that thing. Once everything is all lined up, I cut strips to my hearts content!! I had no idea it had a name. I just call it my ruler with the slots... I bought it on clearence at my LQS because the omnigrid I wanted was too expensive.
