Hey /out/. Is Fiskars X7 decent innawoods axe, or do I need something bigger?

I've recently been chopping couple hornbeams for firewood with an old, smallish axe, and it was insane workout. Later on I borrowed from my neighbour a big, heavy axe and the difference was huge. On the other hand, the size and weight of X7 is very appealing for hiking.

So, is X7 a tiny hatchet that could, or is it a tool for cutting off branches and not much else?
