What is a Knot?
In woodworking, a knot is a portion of a branch or limb of a tree that has become incorporated into the wood of a piece of lumber. Knots are typically darker in color than the surrounding wood, and their grain may not follow the same pattern as the surrounding wood, making them more difficult to work with.
Knots can add character to wood products, and are often used in decorative pieces. However, knots can also weaken the wood and make it more prone to splitting or warping. The impact of a knot on the strength and stability of a piece of wood depends on the size and location of the knot, as well as the type of wood involved.
