Skavd

Skava is Swedish and its common meaning is something like "chafed" or "scraped", but it is also a technical term for carving the logs in a log bilding in order to make them round (or sometimes ecliptic), with a special knife. This was common practice in Scandinavian medieval "cross joint" timber building technique. The presence of skavda logs in such a building will point to a probable dating before AD 1600. From a dendrochronological point of view this means that the bark edge not (surely) present, resulting in a larger time span for the dating.
