schnitting
n.— «Archeologists use a flat-bottomed shovel to shave exposed layers of earth in the squares, to make a clean edge across the surface, and to keep it fairly level. The process is called “schnitting,”according to Dave Hazzard, director of the threatened archeological sites program at the Virginia department of historic resources, and a principal at this site.» —“Artifacts spanning the ages found at Fort Raleigh” by Ed Beckley Outer Banks Sentinel (Nags Head, North Carolina) Oct. 14, 2006.
