A newly designed and easy-to-use increment puncher (in French: minisonde de prélèvement, in German: Zuwachsstecher, in Italian: puntura incrementale) allows the extraction of wood and bark cores from living tree stems to study radial increment, cell-wall growth, lignification and wound reactions. The size of the wood samples are maximal 10 mm in length and 2.5 mm in diameter. The main parts of the puncher are: The punchertube, the guide, the fixing panel with fastening belt and finally the clearing rod with guiding tool.
