well, i have the splitting maul. and love it. i/we go thru 6-7 cords a year (not face cords,real cords). so i split alot of wood.
GET THE MAUL if you rely on wood for heat. if your just going to use one or the other for the fire pit or car camping then the large spltting axe would probably suit your needs better.
it all depends on your needs IMO.
we heat and cook with wood so i/we (at my request the wife bought it for my b-day) decided to purchase the maul last sept. i used a sledge, wedge, axe combo for years. then decided to consolidate into one and choose the GB maul.
bottom line; it's worth the money with the 20yr warr.. and is a damn pleasure to use, i use it everyday with joy. a quality tool in ones hands makes one smile
i've been eyeing the small splitting axe just because i want it, but it will have to wait 'cause i can't afford it right now. don't need it anyway, i just would like to have it for camping and such... any ol' excuse will do
