I am considering a Fiskars super splitting axe. I am concerned whether it will handle the 12-18 inch elm we are, and will be, splitting. Our average round isn't 18" but we have split some that big. With only 4 1/2 pounds will it still do the job? I am also concerned about the 28 inch handle. I was using a 31 inch handle and it felt about right, and safer as the head is out there a ways. Will the shorter handle be a factor in its ability to power through the larger elm, and do you see it as a safety issue in case of a glancing strike. Your input and experience is helpful.
