They pass through a cleft that has been made across a low range of hills, like a kerf in the top of a log, and enter into a lovely territory of subtly swelling emerald green fields strewn randomly with small white capsules that he takes to be sheep.
-- Neal Stephenson, Cryptonomicon
The first chips that flew were ten inches long, but they quickly dwindled as the kerf sank in.
-- Ernest Thompson Seton, Two Little Savages
Kerf comes from the Old English cyrf, "a cutting," which relates to carve.
