I have noticed that when people bore cut a tree they always use the 45 degree down dogtooth cut to release the tree. Saw a guy get his arm broke on Youtube because it pinched and twisted his saw as it lifted and fell. I have done a few lately where I made the bypass cut parallel to and below bore cut, seems to me there is no chance of pinching your saw if you do it that way. Is there a good reason why I should not be doing this? Not a logger, just cutting a few ash trees to get a few bucks out of them. Serious Dutchman, bad side lean and not paying enough attention to how deep I was.
