A sawfiler is someone who works with saws. Just like when you use a pencil and the pencil gets dull and you need to sharpen it, saws also need to be sharpened so they can cut things properly. Some sawfilers use special machines to sharpen the saws, while others use a special kind of file to do it by hand. Either way, sawfilers make sure that the saws are sharp so that they can be used to cut wood and other things that we need in our everyday lives. It's an important job because if the saws weren't sharp, they wouldn't be able to do their job properly and things wouldn't get cut the way they should.
