If you own a chainsaw watch this! vgfzx

I've been cutting wood for over 50 years; this guy knows what he is talking about!I'm a volunteer saw instructor, both crosscut and chainsaw, with a volunteer trail maintenance origination in the PNW. The USFS curricula we use emphasizes the importance of a proper grip on the saw which is as you describe - with the thumb fully wrapped around the saw handles. With the thumb wrapped, there is a mechanical connection between your hand and the saw. With the thumb not wrapped, it's only friction between the palm and fingers and the handle. Students who fail to grip the saw properly will fail their certification class, period, end of story.
