2. Once all the cuts are complete, use the tweezers to slice flush with the surface of the trunk, the over-thickness of the lips of the scar. A useful precaution to take in this case, is to pass the sharp edges of the clamp to the flame or better, with a rag soaked with alcohol. (Be careful in this case not to cut yourself on sharp edges, normally sharpened like razors!). This precaution is of a prophylactic nature and makes it possible to avoid contamination by soiled instruments.

5. The next operation is the most important since it involves completely covering this section with an insulating mastic. Apply the putty with a spatula or a piece of wood. Avoid using metal as much as possible.

6. This putty is a kind of varnish that prevents the wound any contact with air, water or dust, elements carrying bacteria. Not treating a large cut in this way, forces the tree to defend itself by forming, at the edge of the wound, these unsightly lips. The necessary nutrients that he uses for this healing deprive him of a harmonious development and the wound thus formed, in addition to the health risks that it makes him run, harms the aesthetics of his classical profile.
