Let me start off by saying I'm very hard on things. I break most axes within 2 cords of use. I was convinced the x27 with its hollow handle was a gimmick when I bought it. But this thing is awesome. I've used this for 95% of my splitting the last 2 years. I'm guessing it's processed around 20 cords. I can't beak it. Countless overstrikes to the handle. I process my wood on my asphalt driveway. Countless overswings where the head hits the asphalt like the on pictured below that was from today. Only fiskars tool I own so can't talk about the rest of thier line but the x27 is the best splitting g tool I've ever owned by far. Only maintenence has been the occasional sharpening with a file
