UncleJimmy: I'm seeing lots of cross-cut trees showing up now, not really actual wood knots, it shows the heart wood and growth rings....not the same thing IMHO ( 5 years and 2850 days ago )

friiskiwi: I agree;
A knot is a particular type of imperfection in a piece of wood; it will affect the technical properties of the wood, usually for the worse, but may be exploited for visual effect. In a longitudinally sawn plank, a knot will appear as a roughly circular "solid" (usually darker) piece of wood around which the grain of the rest of the wood "flows" (parts and rejoins). Within a knot, the direction of the wood (grain direction) is up to 90 degrees different from the grain direction of the regular wood. ( 5 years and 2850 days ago )

kyricom: I Agree... knots are not cross sections ( 5 years and 2850 days ago )
