The axe has stayed pretty much the same for centuries. But a Finnish inventor has come up with a better design. Your typical axe has the handle directly behind the wedge. This drives it straight into the wood. The new Leveraxe has an asymmetrical wedge that is offset to the handle. This means that the force of the blow causes the blade to twist. This means that the user has to lighten up the grip as it strikes, and that the blade forces the wood apart. There’s a good video of someone easily striking off the sides of a log, and then breaking the log down. This is much easier than splitting wood with a regular axe (and I’ve done it in the past).
