I once lugged around a 30" bow saw, with a big mallet (more of a sledge maybe) and wedges you easily fell bigger trees in a quite safe manner (this was in a forest owned buy my employer at the time, so it was actually paid work, I left the chainsaw at the farm by choice. It was big birches that was going to be dried and used for heating the house). It is hard to find good quality blades around the town I live in now though. And as I usually go by public transport the frowning faces of my fellow passengers has made the big'un a drawer queen, or more of a cellar queen actually.
