Description
A sound knot is a knot in lumber that is solid and firmly fixed in place, and does not fall out or affect the strength or durability of the surrounding wood. It is a natural occurrence caused by a branch that has been fully encased by the growth of the tree's trunk, creating a tightly knit, dense portion of wood.
