How to Use Reversible Cutters

Reversible cutters are cutting blades for routers that create perfect joints. This happens because, when the router is run in the clockwise direction, it will cut a set of grooves into a wood surface. When the router is run in the counterclockwise direction, it will create the exact opposite cut in a second piece of wood. These two pieces can then be joined by sliding them together with a bit of wood glue.
