you've never seen this before? we have router and bridgeport blades in our shop that will do this

It's a triangular bit and the center wobbles so that it fits within a square shape. There are indents cut in the sides of the triangle so that it can cut the metal, but it's essentially triangular.
Still fucking cool.
