Popular Science: To saw different materials, users often need to switch blades. A blade with big teeth, for example, cuts wood quickly because it scoops out a lot of material with each tooth. But those same big teeth make the saw kick back toward the user if applied to a harder substance such as steel.

This saw has a lot of potential especially if they could figure out how to make it cordless. From what I can see, it would be an interesting replacement for a sawzall. Even if it takes slightly longer to cut through something because the double blade isnt designed specifically for it you make up the time not having to ever change blades. The only thing that would terrify me would be if the two blades hit each other for some reason. Ultimately, I would want to try this tool out for a while before I considered buying one.
