That’s very interesting! My pure speculation would be that it’s similar to how Paul sharpens the first inch or so of the teeth at a less aggressive angle for starting the cut. By angling that portion of the saw, your ancestor would know which teeth were sharpened in this manner, and would be able to keep them out of the way once the cut was started. If that was the purpose it’s brilliant! I’ve not seen or heard of such a thing so I’m curious to hear other responses, but your theory of it being used to start the cut makes sense.
