I found this in a box of old tools that was sitting outside. I did my best to clean it up and restore it with the tools I have. The saw also looks different from any other I have seen, and the tip doesn't appear to have been broken off.
These are some pictures of the condition I found the knife in. It was completely rusted shut.


And here are the after shots.





Note the odd shape of the saw.


All teeth intact.
