The axe has a long and distinguished history as a mandatory tool for work and war. It is, in the language of high school physics, an inclined plane (two sided) attached to a level (handle) that allows one to deliver terrific force to a point. In the case of a round of wood this force causes the wood to split. In the case of a Viking holding an axe, heads split even more easily. The axe is what my physics teacher called a “simple machine.” The fact that its basic design has stayed constant for generation on generation attests to its usefulness and efficiency.
A wood burning home depends on the axe and variations of the theme. Our personal collection includes a standard axe, a maul, a hand maul, two hatchets, a collection of wedges and a thing called a “wood grenade.
Recently I took the plunge and purchased a Finnish Vipukirve http://www.vipukirves.fi/english/, a surprising new variation on the axe which increases the ease of splitting wood by a factor of at least two. That is, I think it is twice as easy to split wood with the Vipukirve.
It’s kind of amazing that it took 400,000 years or so for someone to come up with a completely new twist, an axe with a counter weight, that torques hard to the right as the blade makes contact with wood so that you get downward and sideways force at the same time. For someone who enjoys splitting a winter’s worth of wood it’s the equivalent of going from a wooden tennis racket to a one of those Prince oversize rackets that appeared in the 80’s.
The Vipukirve (or Leveraxe) is safer too. It has a longer handle which makes it more difficult to whack yourself in the leg. But what really makes it a safer tool is that you don’t have to swing so hard. Because of the design the Leveraxe never penetrates completely through the wood. In addition it doesn’t get stuck like a conventional axe which often means using wedges to extricate the blade.
Almost as valuable as the Vipukirve itself is the idea of putting your round inside a tire. This is magic. Check the video.
