Thanks loads to those that took a look at this and responded. You know, if it had a little coarser teeth the ice saw suggestion seems plausible. I decided to take this apart and clean it up some to see if I could find any maker’s marks on the metal blade. I didn’t. In the way I received the saw, the handle was more or less straight off the back end of the saw.
When I took it apart, I realized that the blade was broken and originally went further into the handle. You could see the outline on the metal to show that the handle actually was set at an angle to the blade. Someone cut a little notch in the blade to catch the screw to help secure the blade, probably the same guy that did the handle repair. I drew a simple sketch to visualize what the handle might have looked like.
