The History Channel ROCKS! . I was watching a Nuts and Bolts subject on chainsaws's, specifically,, Sthil. It was not boring. They even had some hotsaw champion, but I didn't recognize his name. The factory jobs looked cool...
Its just amazing when we look at how far we've come in 60 years or so, from enormous saws that were 200 pounds, to saws that only weigh 19 or so and have much better performance/safety features.
