The upper cut moves, the lower cut does not move, and the joint point of shear is the base of the tree, causing the bark to be rotted by the lower cut
。
When the knife is not sharp for a long time, it will produce the phenomenon of skin clamping.
:Double blade construction
No skin
Do not hurt the branches
fast speed
。The shear junction of the two knives is in the center of the tree. Even if the blade is not sharp, it can break the bark, so there is no clipping phenomenon
The top and bottom are open blade, so there is no bark rotting phenomenon
Double tool linkage stroke is half of the single tool stroke, so the shear speed is fast and energy saving
