(Phys.org) —Finnish inventor Heikki Kärnä is the man behind the Vipukirves Leveraxe, which is a precision tool for splitting firewood. He designed the tool to make the job easier and more efficient, with no need for an external source of energy. In short, he has redesigned the axe. This is a lever-based axe. The axe head is attached to the handle from the side and not through the center. This results in the center of gravity of the axe head being to one side of the center line of strike. Leveraxe is based on a lever mechanism and rotational action.
