Help with Planer Blades Please

We think that Jan provided those pictures only as an example of "bevel up" or "bevel down" Mark. Your question is a good one though. We had assumed that material was just pushed into the edge but on second thought, they do look like "bits" for a rotating head don't they? We're going to ask the customer and get back with you so thank you for posing the question Mark.
