Nov 27, Open face notch with large opening angle Used for trees on flat and sloping terrain. Opening angle of more than 70° for greater control and precision. The bottom cut is angled downwards from the felling cut.
Mark a line from the starting point to the ending spot of the cut.
The felling cut is in line with or slightly above the level of the directional Estimated Reading Time: 6 mins. The function of the notch is to allow the tree to fall without breaking the hinge prematurely. Typically, most notches today are less than 45 degrees.
