I don't mean to be harsh, but this saw is really not useful.
I've done enough testing to know a few things that affect how useful a saw is.
First, cut of the teeth. The teeth here don't look to be cut into a useful shape, where the edges that come in contact with the cutting material are sharp. Look at the shape of the teeth on a victorinox saw to get an idea of what I'm talking about.
Second, the width of the overall saw blade. The thinner the better, because it's less material you have to remove with the cut. This blade looks seriously chunky.
Third, length of cutting area. The longer the saw, the fewer strokes to make a cut.
I would scrap this idea, personally. I'm not trying to trash your ideas, just give honest input.
