No more dragging and hitting with heavy hammers!

Jonko cone wedge especially designed to use in a tree and to fell small to medium size trees with a slight overhang. Due to one year of field testing different prototypes and different threads we managed to design a good functioning cone wedge. Jonko is the result and can therefore be used in a broad range of applications.
