The ax has finally been revolutionized after a million years: this new model eliminates half the fatigue
Technology has literally sent many tools into retirement, introducing new ones that reduce human fatigue, but some we can say have remained exactly as they were originally created. One such tool is the ax with which we chop and split firewood.
It is an exhausting job that if done without a certain attention and criterion can also damage your muscles.
Fortunately, a Finnish company has come up with a revolutionary idea that will improve the life and health of lumberjacks or anyone else who has to cut a supply of firewood ...

Tree trunks are split through the application of force on a sharp ax blade. A small change can save a lot of effort.
The idea comes from the 74-year-old Heikki Karna, who thought of revolutionizing this ancient instrument when he had to deforest by hand a vast woodland area.
The task proved so tiresome that the man decided to think of a modification that would allow half of the necessary physical force to be employed.
This was how Karna arrived at the idea of inserting a mechanical lever into the ax and to completely change the position of the blade.
Now the prototype has been realized and is being sold by Leveraxe, a fully functioning business company.
These two changes completely modify the physics of cutting wood.
In particular, Heikki Karna's ax leverages the action of a side lever to easily cut the trunk into several sections. When a trunk is hit, the blade moves sideways due to its particular position, thus separating the trunk into several pieces without the need to exert excessive force, and above all with a single stroke.
Let yourself be astonished by the efficient operation of this unique wood cutting tool as displayed in this slow motion video!
