I just bought the Granfors Bruks Mini Hatchet (left) to keep my GB Hunter's Axe company. These are made in Sweden and are very interesting tools. Heads forged on old power forges, each axe/hatchet comes stamped with the maker's mark.
I've only used the Hunter but they hold an edge very nicely. They were both shaving sharp out, of the box. The GB axes/hatchets are very nicely balanced, and compared to the Home Depot special, they are extremely light weight. The Mini Hatchet is small enough to slip into the back pocket of your jeans (use the sheath!!!), and light enough to not drag your trousers down. No "Plumber's Cleavage" from this riding in your back pocket. They are kind of pricey, but IMHO, very well worth the money.
Axes aren't sexy like blacked-out fighting knives and survival blades, but if I had to grab only one blade, before bugging out, I think I'd take my Hunter's Axe.
Note: shown with my USMC Kabar to give an idea of the scale.
