Great tool but like all other tools it has its strengths and weaknesses.
I left my axe at home and only took my hook for a few weekend trips out, i missed my axe.
Its a lot of weight and can be tiring quickly. My favorite use is for splitting and roughing out the belly of a bow. Hedge laying folk are the guys to watch with these tools.
Edit, its also a lot of biting edge very close to your fleshy bits.
