Logging Terms  - K -

KERF: Space resulting from the cutting of a saw chain. The width of a cut is referred to as the kerf.

KERF DUTCHMAN: A special falling technique in which the constant relationships of the face, holding wood, and backcut are intentionally altered to solve a particular falling problem. The faller can, with the use of the Kerf Dutchman, force a tree to jump off the stump. If understood and properly used, the Kerf Dutchman can in specific instances solve problems of breakage and crossing roads or creeks.

KICK-BACK: A strong thrust of the saw back toward the faller generally resulting from improper use of the nose of the bar or the pinching of the bar in a cut. Kickback causes loss of control of the saw and this in turn results in numerous saw cuts each year. Kick-back also refers to a tree jumping back over the stump toward the faller. This kind of kick-back generally results from a tree being felled into standing timber and/or lack of stump-shot.

KICKER: A piece of the face, or an equivalent object, placed in one side of a face cut to pull the tree from its lean as it falls.

KNOB: A metal ferrule attached to the end of a line.
