Hi,
Just wanna say how glad I am for choosing this, somewhat more expensive option at the hardware store over some generic old-fashioned axes. Indeed it's like this thing contains magic dust that makes splitting logs a breeze.
Some observations: There are many people longing for a slightly longer handle, while many people also seem to use it to break rounds on the ground, without using a block. Perhaps there's a correlation. As my old folks taught me, firewood needs to be chopped on a block, otherwise the blade will hit the dirt (or in worse case your foot) and dull. Breaking really huge rounds that are difficult to even lift and place on a block could be easier to break on the ground with a longer-handled axe that's designed for breaking huge rounds on the ground, but that's not really what this tool is about.
Realistically, this axe is designed to split normal sized, 10-20" diameter firewood on a chopping block. For that purpose it's excellent, and I honestly hadn't ever missed a longer handle (I'm 6'2"). Indeed it looks like there'd be a market for Fiskars to sell an even longer and heavier axe for breaking the really big piece of wood without using a block, but that's just not precisely what this product is designed for. If it was longer and heavier, then splitting smaller firewood wouldn't be as effortless. There are always tradeoffs.
