The second blade seems like an attempt to combine a skinner style point with a draw type or splitting edge closer in. IMHO, the knife is too much a compromise and not enough purpose. Maybe a good theory that just doesn't work in practice. Not sure I would find much use for it.

For a saw, I prefer a chain saw; the kind that fit in a can about the size of a snuff tin and is drawn back and forth using your hands, or a makeshift frame. Small enough to EDC if you want, but very functional, at least for cutting something softer than steel.
