Those were tiny lil trees he was cutting. Cool video though. Did anyone else notice the very last cut (at the 10:00 mark) where he upcut through the log and put the tip of his bar either into or very close to the end of that other log, creating a very high likelihood of kickback? Perhaps they should have cut the film off 1-2 seconds earlier...
I don't speak the language, was that addressed in the film? Did he create that kickback situation on purpose to demonstrate what to watch out for?
