I don't know either, but they're just not very well-filed teeth. I frankly can't imagine that the saw in the photo Stewie posted would saw as well as one filed by a really good saw guy. Just don't believe it. If it's true, then we can all just turn a chimpanzee loose with a saw file and not worry about a thing.
