Fiskars knows cutting tools and these axes prove it!
We will never buy another axe besides this line of axes. Talk about sharp and seriously effective! There is something about the technology of how these axes are designed built that makes them just cut through firewood like no other axe we have ever used. They keep an edge well but in case you need to sharpen it, Fiskars also sells a sharpening tool.
We have purchased and used both the X25 (28-inches) and the X27 (36-inches). They both work very well. We prefer the X27 for splitting larger chunks or rounds and the X25 for more everyday splitting when you just need some smaller chunks or kindling.
