Title: Wood Axe Reinvented.
Post by: Burt Gummer on April 25, 2014, 09:14:39 AM

Yes people some crazy guy in an other country (Finland) reinvented your log splitting axe. It's called the "Vipukirves" or lever axe.

(http://www.geek.com/wp-content/uploads/2014/04/Vipukirves-590x330.jpg)


So what makes a lever different than a wedge in this scenario? The Vipukirves still has a sharpened blade at the end, but it has a projection coming off the side that shifts the center of gravity away from the middle. At the point of impact, the edge is driven into the wood and slows down, but the kinetic energy contained in the 1.9 kilogram axe head continues down and to the side (because of the odd center of gravity). The rotational energy actually pushes the wood apart like a lever. A single strike can open an 8 cm gap in a log, which is more than enough to separate it.

Looks like a MUST have!

I wonder what the logs are? Oak?

I wonder how dry the logs are. I tend to split 1/2-2/3 dried logs, stack and then let finishing the drying process happen over a 2-4 month period.

€203- though (~$265-)...Ouch!
