That Dexter mat cutter is still being sold, believe it or not, it is a stone age tool. It works great if the blades are sharp and you are careful and only want to do one at a time. It's not for the weak though, a younger person, before carpal tunnel, arthritis, and general bone and muscle disease sets in will enjoy the work out. I used one in college, it's basic but a Pinto not a Cadillac. Get a better unit, there are many available, or have them made. Get a dry mounting press too, they are worth their weight in gold. I have a 16x20 and a Seal tacking iron, also necessary.
