What's the difference between a hatchet and a camp axe?

Hatchets are generally 12-14 inches long with a head around 1.25-1.5 lb, swung one-handed for kindling, limbing and light chopping. Camp axes (sometimes called boy's axes or 3/4 axes) run 18-22 inches with a 1.75-2.5 lb head and are swung two-handed for real splitting and felling. If you're mostly making kindling at a campsite, a 14-inch hatchet is enough; if you're processing larger firewood, step up to a 19-inch camp axe or a dedicated splitting maul.
