Com: Mike : He didn't hit another branch with the tip as it has been mentioned in the comments. While kickback happens mostly that way, clearing a chain link metal fence with a chainsaw is just begging for it.
If you take a closer look, that's what he hit there, hard not to get a big ass kickback. With that type of judgment, a chainsaw is not the best tool for this rather lucky feller. Glad he didn't get seriously hurt though, at least he learned something valuable.
Com: Lynsey : He is very lucky to escape that alive! A tree surgeon near my area had this happen to him and sadly died after slicing into his own neck. Seeing this video has made me see how fast and sudden these things can turn into a death machine! Scary!
