You can buy a custom axe with the head tempered by Bavarian elves and a handle made out of left over Stradavarius wood, but you won't find an axe or splitter that does better than the Fiskars brand.
And they are inexpensive.
I have the shorter "boys axe" that I carry in my trucks, and the same size splitter and a longer full size splitter. Best I've ever used in all cases.
