In my part of the national forest, chainsaws are banned. All forest workers use long hand crosscut saws. For cleaning trails. And all other uses. A pre WWII 6 foot crosscut saw, can be worth as much as $1,500. The old saws use higher grade of steel. Yes they are still making new one, but everyone says they're not as good.
@corlin: Affirmative. I'm old, but I can handsaw and hatchet/axe for about three hours at a time, with a 45min. to 1hr. break between. That's what I did today. Of course, I had to shower twice, but I got the stuff done. LOL

Young forest workers have to take and pass a 4 week field training, and safety test. Before they can use one.
If you learn how to properly use one you can saw all day long.
