I have researched this and have come up with nothing. According to my calculations it is not new. Apparently at some point someone thought a cast iron handle would be better than wood. But it seems that did not catch on.
Perhaps it has something to do with the unusual saw tooth pattern. The saw teeth are much larger than those of a saw for cutting 2x4s. Looks like it was for cutting small logs and branches.
The saw blade is about 30" long which is on the long side for a one handed saw. I'll go with the power tools myself.
