Anybody know the correct way to file/sharpen a chain saw's chain? I realize shops do this for a fee, but it'd be a nice skill to have for GP. I have a few saws laying around that need sharpened.

Thanks in advance!

 

It's really easy, you just need a special file that fits the teeth properly, and basically just keep working it down at about a 30 degree angle till the tooth gets a fine edge back on it.

It might be cheaper just to buy new chains.
