Hello Lois Lane

Thank you for your opinion about my invention.

Birch is the most commen fire wood in Finland. Also pine and fir are widely used. Then there are numerous amounts different kind of other trees which do not have very big significanse.

When I started to think about better way to split wire wood I made many kind of experiments. Security was one of the things that worried me a lot.

There has neve been any safety elements before in the hand operational fire wood splitting.

I attached the tire to the chopper block and this way I got the opportunity to series split many blocks one after an other without touching and continuously lifting them up to the chopper bkock.

I do not recomend the tire with the conventional (wedge)axe because it penetrates all the way through the block and so there is a big possibility that sooner or later there will be part of the block under the handle that may get broken or you will get strong chock to your hands. The blade of the Vipukirves/Leveraxe allways remains on the surface of the block so that the handle very seldom even touches the block.

Even if you do not use the tire on the chopper block, the block you are splitting remains on the chopper block, because the Vipukirves/Leveraxe causes all the power to the left. This happens so fast that the mass of the splitted block will keep it in it's position as long as there is anything left to split.

I have tried to attach some videos, but haven't found yet the way, how to do it.

If you Google or use some other searsh machine, you can find a lot information about this invention.

Also YouTube is very handy to see the videos. Search by words Vipukirves and Leveraxe.

Based to the feedback, what I get nearly daily bases, The hard wood is not a problem any more.

I ship the AXEs all around the world. The price has been the same over eight years. Anfortunately there is the big water between us which means some shipping expenses. Also the value of USD. is not very favoufable against EUR, but I cannot effect to those things.

I correct here the opinion of Nathan Natas. The total price including the shipping is 203 EU. This equals 278.66USD. The price is tax free.

Hello

Thank you for your interest in my invention Vipukirves/Leveraxe.

The conventional axe was invented by the man in stone age. The axe blade was made of stone. Today the same blade is made of iron. Where is the development?

Is there any? Threre has been thousans of attempts to get rid of friction. Atleast the same amount of attempts have been in trying to add the splitting force.

First time in the history the above mentioned problems have been solved.

The friction is neally non existent in the Vipukirves/Leveraxe and the splitting force is many times bigger than in the conventional axes.

How can this be possible? Because the eccentric blade there are some advantages which have never been available before.

The blade rotates at the fraction of a second at the very moment when the edge of the blade touches the surface of the block. It penetrates on an optimum strike only 5 millimertes (a quarter of an inch)into the block. This was the friction part. The blade leans to the right, the leverage happens which multiplies the splitting force many times bigger, all the kinetic energy turns to the left and pushes part of the log away.

The blade will not get stuck into the block. It stops on the top of the block. All the above mentioned happend fully automatically. Important is that you hold the handle as gently as possible to allow the rotation.

The Vipukirve/ Leveraxe have been on the market over eight (8) years. There has happened NO accident. In fact, first time in the history of axe-like tools, there are safety efements build into the blade, which stop the blade. There is no fear that you could hurt yourself as with the conventional axes.

Well. Let this be hopefully fruitful start to our conversation. In case somebody would like to get more infotmation, I will be delighted to answer to any of your questions to the best of my knovledge.

There is a lot information about this invention in Google and other search machines. Also YouTube know this.

Yes, I am the man in the video. I am also writing by my own name because I have no need to be as inkognito.

I have alot to tell you about the easiest way how to split firewood manually, only if you allow me. I am not willing to argue with anybody and I hope that there will be preferebly questions instead of arguments.

Best regards

Heikki, the inventor
