Sounds like there is some confusion here. The new olfa mat folds in half
http://www.joann.com/olfa-folded-cut.../14427736.html -this is not the omnigrid mat.
i got one about two months ago for classes. I've tried it out and am very impressed. Since my current Olfa is 5 years old and still like new, I hope for the same on this one.
