PUT THIS ONE IN YOUR WILL, IT'S BUILT FOR A LIFE TIME
This cutter provides the accuracy you are looking for. The factory-calibrated to +/.005” cuts at a slight angle for but to seams, and is essential for matching edges in pattern work. The 12 3/4" blades are made with a special high-carbon steel edge that is sharp and long-lasting. The cutter also has a locating stop for repeat cuts at the wall. ( which I have never used.) Here is a good tip, when cutting a wall, put 2 tiles in at the same time. The blade height adjusters work very well on this cutter. In about a year most people lose the 45 degree agonal guide, a pair of vice grips works just as well. The case is a class act and holds up very well.
