The new and improved Vipukirves(Leverax) uses a “unique lever action” that is “considerably stronger than a traditional axe” to separate a log into sections, allowing the user to easily create a pile of firewood in seconds. The ax is painted in traffic-light red and yellow to make it easier to spot if left on the ground.
