If you look at the end fiber of any boards from an array, you can replace one -year rings (in some breeds they are more pronounced). The empirical rule suggests that they try to straighten when the wood dries. This will tell you which way the board will be tagged. If the annual rings are long, then this is the “Tangential Snovka” board and, apparently, will be more to bore than a board with short annual rings (which is called the “radial cutting” board).
