Tight Encased Knot

A tight encased knot is a type of knot in wood that is surrounded by cambium layer, which is the layer of tissue between the bark and the wood of a tree. This thin layer of bark or cambium serves to encase the knot, providing a protective layer around it.

Despite the presence of this encasing layer, the knot itself remains tight and securely fixed in place within the wood. This type of knot is typically found in trees that have experienced some type of injury or stress, such as wind damage, insect infestation, or disease. When the tree responds to this stress, it may form a knot as a natural part of the healing process.

Tight encased knots can add character and visual interest to wood products, but they can also weaken the wood's overall strength and stability, depending on their location and size. As with all knots, it is important to consider their impact on the quality and integrity of the wood when using them in woodworking projects.
