I'm not sure if I made it clear enough in the video, but the primary knife is the one that should NOT have any bevels. You SHOULD have bevels on the stab knife, however. Do not remove those.
This video just covers some basics about chip carving. To learn more, I highly recommend the book by Wayne Barton called The Complete Guide to Chip Carving.
