Foam Board Rabbet Cutter
A key tool for architectural model makers and display builders who work with foam board. The Foam Board Rabbet Cutter slices a perfect 3/16" notch out of the back facing. Both cuts of the 2-step process are made by one replaceable, single-edge blade to make perfect joining corners.
The small Rabbet cutter fits in the palm of your hand and the blade is contained inside to make it safe to handle. It includes one single-edge razor blade, but you will need to purchase more separately. Changing the blade is easy, but requires a common Phillips-head screwdriver.
