1. More effective than a traditional axe

The other reason for the slow progress with the traditional axe is that actually a lot of time is used for lifting the split wood back onto the splitting block. With a traditional axe you are forced to always hit in the middle of the wood. Thus both split woods fall to the ground and you need to lift them up to continue splitting the first one and then the second one. It is quite laborious and straining for the back.

Leveraxe is based on a lever

Leveraxe is based on a lever mechanism and rotational action. The operational principle of the Leveraxe is totally different from the traditional axe.

The Leveraxe is of a brilliant new design. The axe head is attached to the handle from the side and not through the center. This results in the centre of the gravity of the axe head being to one side of the center line of strike.

2. Leveraxe can handle large and difficult logs

Logs are split usually with the first strike. The axe won’t get stuck inside the wood. Time is not wasted lifting the woods back on the chopping block as the axe holds the log steady for the next strike.

You no longer need to aim the first attempts at the centre of the log and try to split it in half. With the leveraxe you can start from the edges and easily chop away the easiest pieces first, reducing a large log to small pieces with ease. This way it does not actually matter how large the log is.

3. Does not require a lot of power

Leveraxe head is eccentric by design and thus the center of gravity is to one side of the handle and the line of strike.

Upon hitting the top of the log and penetrating it slightly, the leading edge of the axe head begins to slow down. Where the axe blade widens sharply it stops the axe’s penetration.

However, the mass of the axe head still has kinetic energy and the off line center of gravity forces it to rotate eccentrically down towards the wood. This rotational movement causes the leading edge, or sharp edge of the blade to turn in a lever action, forcing a split with all the force of the kinetic energy of the axe multiplied by the leverage of the axehead.

4. Leveraxe is safe to use

Safety has been one of the main principals when designing the Leveraxe. Thus it can even be put in the hands of women and children for whom a traditional axe would be hard and dangerous to use.

With Leveraxe, it is impossible to strike through the log, because Leveraxe will stop on top of the log. The Leveraxe also does not bounce wildly as might happen with traditional axe. The axe changes the kinetic energy to rotational motion and is much easier to control. It is much rarer that you would totally miss the log, because the sideways wing on top of the axe and the stopping knob beneath it ensure the axe will catch the log even if the striking edge would miss it. Of course, it can not help you if you miss the log by a mile, but that rarely happens.

5. Does not get stucked in the wood

The widening of the axe edge helps in initiating the rotating motion and prevents the axe from getting stuck inside the wood.

The 1,9kg axe head has a significant amount of kinetic energy when it begins the rotational movement. While the centre of gravity of the head continues first to the right and then downwards the edge moves in a rotational direction to the left. This movement uses the rotational torque to split a log and push it away from the wood. In total the edge opens the wood by 8 cm.

6. Leveraxe can chop even on the rocks

With the traditional axe you are almost always required to strike near the middle of the log. Hitting closer to the edge would be dangerous because it is too easy to miss the log or the axe will bounce wildly from a non-centred strike. In both situations the results can be dangerous. Unfortunately, as we all know, splitting a whole log when hit in the centre is the most challenging task. When you have been able to split it in two, the rest will go much more easily.

With Leveraxe you won’t need to take the whole log head on by striking in the middle. Instead, you can easily and safely start splitting suitably sized logs from the sides by striking closer to edges. No more needing the futile first heavy strikes just to get the log split in two.
