I am planning to build a Verge Escapement for a Seconds Pendulum.
… Yes, I know there are much better timekeepers [this one is for 'research'].
I am having some difficulty understanding how a rotating cutter can produce the required surfaces. [maybe I'm just being thick].
The process is demonstrated in this YouTube video:

But I cannot see how the radial surface of each tooth is maintained when the next tooth is cut.
My wheel will have 15 teeth, and should be very similar to the one in this video.
For 3D drawing, I only have Sketchup [v8 Pro], which is driving me to distraction, trying to 'model' this apparently simple piece. … If someone with proper 3D software could model the cutting of two adjacent teeth, I would be most grateful.
