Has that cut been referred to as the Golden Triangle cut, or something similar?
As I understand it...
The two bisecting beaver cuts are the face. The tree falls in line with the apex of the triangle formed by the two faces.
As you make the back cut, the length of the hinge becomes shorter and shorter as you cut, thus allowing the cutter to chase the hinge while reducing the risk of barberchairing.
(BTW, I love the term, bisecting beavers, where else would you hear that?!)
