I didn't realize we had an axe thread here. I split all my firewood with axes. have since I was a kid, Dad owned a wood heat house. swinging a collins maul was his way of keeping me out of trouble...
years later I got into tree service and selling firewood. I can out split a hydraulic splitter for the first hour. my axe of choice? a Mega Maul like Drives posted. bought in the 90's it wasn't the longer handled Stoich or however it was spelled. since someone else posted a fiskars and Drives asked how it performs....
my axe of choice now? a fiskars X27. 36" handle, 4-1/2 pounds. Ive split 5 cord a year with it for the last 10 years. never given me a bit of grief with the non traditional handle. I found this after buying a house and being on the chainsaw and Hearth forums and people raved about them. having used many of other axes in my 38 years of existence and primary source of heat being wood since I was born, I honestly can say that no one makes an axe that compares for splitting. for chopping down trees, not too sure about that. I'm a chainsaw guy.
with that said... I'Ve tried my hand buying a few others, as well as restoring my grandfathers PLuMBs, and acquiring a few others along the years. The fiskars x25 was a 27-28" handle. I didn't prefer that one. Gave it to my brother which he loves. I typically won't split on a splitting block and the shorter handle gave my shins and feet fits while blowing through wood. I picked up the X15 campers axe, as well as the X7 hatchet just because they X27 works so well.
OF my old axles...my grandfathers plumb. My father 6lb collins maul. a GransforsBruk felling axe, and a couple of no name boys axes, hatchets and normal axes. about christmas time I picked up a couple Husqvarana's. one is the very heavy hatchet and the carpenters axe. I have not used thus much, but broke them out to fit the handles to me this past week. I'll get most of them together in my tool box setup instead of piled in random corners of the garage.and post some pics.
I did a Youtube video a few years ago comparing a Fiskars X27 to a Stihl Pro splitting axe, and a Husqvarna S2000 splitting axe. and heres a link to the Fiskars if y'all want to watch and can stumble through my nervousness on camera.
so for now, heres the newest Husqvarnas.
