What size axe do I need for car camping versus backpacking?

For backpacking where every ounce counts, a compact 3.5-inch-blade hatchet like the Gerber Pack Hatchet is the lighter, pack-friendly choice. For car camping where weight is less critical, a 14-inch hatchet handles kindling well, and a 19-26 inch camp axe gives more leverage for splitting larger pieces around the fire.
