I use a Fiskar X27[0] splitting axe and swinging that into a 12" round log of white birch or white spruce at -30C to -45C is like cutting through butter.

Yeah, but that's cheating. Anything goes through white birch like butter.

I can also confirm that the Fiskar X27 is awesome ! I initially was skeptical when I read the reviews online but once I used it was so great. It saved me a lot of time and energy.

Another vote for the Fiskar X27. I haven’t used anything else for a few seasons now.
