I recall watching a Modern Marvels episode on the history channel about logging.
They were talking about a large machine that grabs trees saws off the bottom, debarks them and cuts them in to log sections in a rapid fashion with a very large chain saw.
They were saying how the chain saw had teeth on every link unlike a "normal" chain saw that has teeth on every other link.
I'm wondering, is it possible to buy a chain that has teeth on every link for a hand held chain saw?
