If the only thing you’re doing is splitting, a splitting maul or splitting axe works best. Splitting mauls are more efficient for large rounds, but their weight and length require strength and practice. If you need an axe that’s close to a maul without the heavy maul head, take a look at the Fiskars X27 Super Splitting Axe. Splitting axes aren’t as efficient on large rounds but work well for splitting standard rounds, making kindling, and using for general purposes.
