It does look like it works amazingly well. You can tell he's not really using a lot of force to split the wood. Kind of spendy but worth it if it works.

It is not so much as the axe, rather the type of wood used. You can easily hear how dry it is and looks to be knot free. Some wood species like this splits very easy.

There are other videos on YouTube showing a person splitting wood the same way but with a regular axe.

I would like to see a demo using some different wood such as oak that has totally different characteristics when being split with an axe.

(my third try at a measured response:)

1. I guarantee that this will work as advertised if you purchase warranty approved wood from my woodpile (shipping extra).

2. I guarantee that if you replace "Physics-exploiting axe splits wood in record time" with "Sucker-exploiting axe splits fools from their money in record time" you will achieve a new level of enlightenment.

3. I guarantee that I will pick up one of these at a garage sale for $10 or less, in 5 years or less.

Oh yes, try this on a piece of old growth hemlock fir, the kind with a 1:20" grain twist and three knots per square foot circumferentially. That was the kind of stuff dad would bring home for us from the Weyerhauser reject pile to cut up into firewood, the kind that took 3 wedges and an 8 lb maul to get through.

The ergonomics do not seem to be the best. The off center CG will hurt your swing when you need more force for wood that does not split so easily and with most chops the axe twists away to almost 90°. I doubt that it will feel well with a medium powered swing.

It's all bent out of shape! Everyone knows that axes are not supposed to look like that! Gadget alert - just think of how many more useful ways there are to spend the money required for that item.

With tough items, I just use a splitting wedge and a sledge hammer, if necessary. Much cheaper

Or chewy red fir. I remember 3 wedges from both sides of the round and a maul. Almost lost the wedges.

A rented log splitter works everytime.

I read about these 6 years ago on bushcraftuk, so they are not a new thing.

Not sure I like the look of them, with the constant twisting as the asymmetric head hits.

I am still working on the original 1/2 cord of already-split wood I bought 30 years ago. Yeah, we don't build many fires here...
