The Peanut Gallery
Oh, we have a 3.5 lb splitting axe, a 6lb and 8lb maul. The 6lb has a much longer handle and it is slightly easier to use. But it isn't the maul. It's the wood. It's fresh Fir. It is very wet, springy, and full of knots. Many folks outside of the PNW don't realize how knotted up Fir can be. Just look at the other vid of it in hardwood.
Never split any fur, but we have black oak (black jack) around these parts, and if you get a knotted twisted one, you'll be there all day. Once it starts to split, the stringy fibers still hold it together. It and hickory are about the toughest firewoods I've dealt with. Of course, if you get straight grained hickory, it splits as easy as anything. All depends on the tree.
