I have loved my 30 x 36 Dritz's for over 20 years. They are 1/8" thick and I use them on my dining room table for all of my cutting. Put me on the list of those who think the Olfa is too thin. It's less than 1/16" while the Dritz are a generous 1/8". I use the Olfa only to take to classes and I always think I'm going to cut right through it when I put a lot of pressure on the cutter.
