    I'm starting to feeling like I've been punked. The more I think about it, it seems impossible for that straight blade to make such a tight curve like that. I believe you, I think, but ... this isn't April fools is it?

    Real, the progressive raising of the blade creates a curved bevel on the outer cutaway piece. The inner stays smooth. It would not work as a one shot cut so the raising makes it possible.

    Then you should try making a round wooden bowl with a table saw:

    or a sphere with a circular saw:
