Yes it's called a dovetail, when dealing with trees to small to proper back cut and too large to manhandle over. It allows for wedgeing over without getting your bar pinched.OK, another learning situation. In the group of photos above felling the small aspen. The last picture shows a cut I've never seen. I'm assuming the notch is made first, then the plunge cut in the middle and the wedge driven in, and then the two side cuts made? Is that correct. Purpose is to fell the tree in a certain direction, but diameter of the tree doesn't allow driving the wedge behind the bar like traditionally done, correct? I guess you are extremely careful sneaking up on the "hinge" when making the side cuts?
You do your face notch, plunge through the center of the notch to the back slip your wedge in the back in the kerf you just made. Then with you bar tip pointed towards the notch come in on each side * don't forget to leave a hinge for control*
justve where your wedge is about and inch. Make your side cuts so they are a hair beyond where the wedge is but not all the way across the back. When you tap tour wedge in it should lift the tree over leaving a dovetail and your bar won't pinch.
I think that describes it well. If not I'm sure someone will correct me.
It's really usefull on the smaller diameter trees. Try it sometime, it's another tool in your falling toolkit
