The Bottom or Undercut

The undercut is the second of two cuts that result in a V-shaped notch.  The notch is made on the side of the tree facing the direction that you want it to fall.
The Correct Cut
1. Starting Point
Very Important -- begin at the level that will create at least a 70 degree notch opening
2. Angle of Attack
Important -- cut upward at a 20-degree angle
3. Ending Point
Very important -- stop when the cut reaches the end point of the face cut
