I have two. One needs to be re-hung and I've never swung it. The other, I've split maybe 3 cords over the last dozen years with it. Not really a splitting axe and not too wedge shaped, but too thick to be anything but a splitter. Heavy-ish. I think it weighs more than the 3.5lbs often reported, but I've never actually weighed it. Works well for the occasions I use it for the uses I use it for. My dad put an edge on it long before I could swing it and I think that was the last time.
They don't seem to come up nearly as often as the little hatchets, the cruiser, or the hudson's bay, but they also don't seem to command near the same prices. I keep mine because of nostalgia and because it doesn't seem right to take a fiskars to the cabin where this axe resides.
