I bought this to maintain the single track motorcycle and mtn bike trails I ride (its private and I am the only one keeping it up). It works really well on 4 and 5 inch trees.  The larger, old downed oaks are another story, they are like flint and nothing would cut them.  Some people have noted casting flaws in the metal, but that is silly, its an axe and not Wusthof kitchen knives.  Its a little smaller than a full size axe, and a bit larger than a hatchet.  Nice size for me to carry on my bike but still gives me enough leverage to get a good swing with both hands.  Dont buy it to cut firewood for your home, but to keep in the camper, under the truck seat, or to clean up around the house, its great.
