Skavd

Skavd is Swedish and its common meaning is something like "chafed" or "scraped", but it is also a technical term for characterization of logs in Scandinavian medieval "cross joint" timber buildings, when they are carved in order to make them round (or sometimes ecliptic). It was done with a special knife. Skavning was common practice in "cross joint" timber buildings technique until about AD 1600, and therefore is a sign which may point at a rather old dating. From a dendrochronological point of view this means that the bark edge not (surely) is present in such buildings, resulting in a bit larger time span for the dating.
