A good rule of thumb for all felling scenarios is to make the depth of the face cut or undercut, which is your directional angles notch face the way you want the tree to fall, roughly equal to 1/3 the diameter of the tree. [5] Additionally, one should leave about 10% for your holding wood or hinge wood to direct the tree on its way to the ...

The undercut or notch cut is the guiding or aiming slot for the tree and is a V-shaped notch placed on the side of the tree in the direction of intended fall. [4] The back cut or felling cut is made on the opposite side of the tree of the undercut and is cut through the base of the tree severing the “hinge” holding the tree up. [4]
Cut-to-length logging is the process of felling, delimbing, bucking, and sorting (pulpwood, sawlog, etc.) at the stump area, leaving limbs and tops in the forest. Mechanical harvesters fell the tree, delimb, and buck it, and place the resulting logs in bunks to be brought to the landing by a skidder or forwarder. This method is routinely ...
While the perceived risk of death by falling trees (a part of the "tree risk" complex) is influenced by media and often hyped (the objective risk has been reported to be close to 1 : 10.000.000, almost as low as death by lightning), [6] singular events have encouraged a "proactive" stance so that even lightly damaged trees are likely to be removed in urban and public traffic surroundings.

Steel axes were important in superstition as well. A thrown axe could keep off a hailstorm, sometimes an axe was placed in the crops, with the cutting edge to the skies to protect the harvest against bad weather. An upright axe buried under the sill of a house would keep off witches, while an axe under the bed would assure male offspring.
