Spoke wrench?
Got my vote. Not a very easy one to use, though....Spoke wrench?
this is an antique saw set. the notches are placed over the tooth in a saw blade and the tooth is bent away from center just a tiny bit every other tooth is bent to one side. The saw is then turned around and the remain teeth are bent in the same manner to that side. When a regular hand saw has been properly "set" you should be able to slide a sewing need along the top of the teeth from end to end with it sitting in the slight V created by the "set" of the teeth. 'Setting" the saw teeth in this way makes the cut or "Kerf" slightly wider than the thickness of the blades body and lessens any drag on the saw and lessens the chance of the saw binding in the cut.

You can find more information here "Saw Set Collectors Resourse" this is about the best site for anything to do with antique saws and the tools to service themThank you Leon. Much older tool than the modern saw set. Any guess on the vintage?
