An axe that twist through 80 degrees on impact? Hasn't that got to hurt your wrists?
Not that you'd get a worthwhile power splitter for £188, I built my own rotary spiral screw splitter for around £350 including a new 9.5 hp engine.....
at the end of the day, not impressed, FAIL
I find my long shaft splitter works just fine, had it almost 25 years now and it's still going strong, never sticks and never needs sharpened.
There are always a few long shaft splitter resistant rounds in any load mind, I just throw them to the back of the shed and make a project out of them, they all split eventually.
My longest lasting shed pig was from the big gale of 2006, a gnarly knuckle of beach that finally gave in to a few well placed thumps back in the tail end of last year. Quite a sense of satisfaction gotten from cracking that uncooperative sod.
I have had a few of those - still have a few - they end up on the "stag beetle" pile (a pile of nasty, rotten, gnarly, cross grained and otherwise awkward wood that I leave for beetles and other critters to eat and lay eggs in - the woodpeckers love it). The stuff I want to burn thats like that I just cut up with a chainsaw now - so much easier - and its usually only a few bits in a load.
Depends what you want it to do - mine works just fine. It doesn't split anything I can't split by hand - indeed with 4 steel wedges and a 10lb sledge I can split huge knotty rounds - but with the hydraulic splitter I can keep going all day - which I can't with the maul or axe
