The term "Sabamiki" means "split trunk". It is a deadwood technique that creates a deep wound in the trunk of the tree, giving the impression of a lightning strike or an old injury. Sabamiki is used to enhance the aesthetic appeal and the illusion of age of the bonsai. It is usually done by removing the bark and carving out the wood with a drill or a knife. Sabamiki is often seen in coniferous trees, but can also be applied to deciduous trees.
