I have the Gransfors Bruks Large Splitting Axe. Hand forged by Rune Andersson, whose initials grace its head.
It is a wonderful, finely crafted tool. Far more effective than a regular axe due to the compound curve of its profile and its razor sharp edge.
It is a joy to use.
On our annual, extended family, camping trip in Pennsylvania each year, everyone volunteers to split wood, just to try out the Gransfors Bruks. And they all leave their mauls, and other axes in their camps, because the GB is just so...sweet...
