pine knot

Dense wood swirl

A pine knot is a dense, resinous section of pine wood where a branch once joined the trunk.

These knots resist decay long after surrounding wood rots away, leaving hard nodules in old stumps and logs.

Because of their high resin content, pine knots burn hot and were traditionally used as fire starters or torches: We gathered pine knots for kindling.

In lumber, pine knots create weak points and irregular grain patterns.
