poorboy,
I have a Stanley double bladed ax that has served me well. I also have a cheaper [no name] ax and you can tell is softer metal - - it sharpens & dulls quickly. The Stanley, however, holds a sharp edge much better. I've had the Stanley for 20+ years & have been through 2-3 handles [due to operator error, my handles 'wear out'].
I use a splitting maul for splitting most firewood, but will also use the Stanley for smaller pieces.
Good luck.
