kerf (KURF) - n., the groove or slit made by a saw (or other cutting tool), an incision; the width of such a cut; the act of cutting or carving, the act of making kerfs.


The importance of the width is as a measure of how efficient the saw or whatever is. This is an old one -- it goes back to Old English, where it was spelled cyrf (and variations thereon), a cutting, a cutting instrument, and a cognate of ceorfan, to carve.
