A discussion of the different number of teeth and uses would have been helpful. For example, a 14-tooth blade cuts quickly, but rough. A 24-tooth blade is useful for framing material, 2 inch stock, a 40-blade is good for sheet (plywood) and an 80-tooth blade is used for miter cuts. Whereas, MDF is cut with 90- to 120-tooth blade. More teeth, the cleaner the cut. Otherwise, a good video.
Watching David cut a piece of wood with the circular saw on the floor is enough to make my back ache. I always use my circular saw on my workmate.
