>>312551While I am a fan of a good Kuk...it is, decidedly, not the only knife you'll ever need. It's a decent chopper, and frankly it tends to replace a hatchet in my kit.
The inner curve should be kept sharp, as it works well as a draw knife.
But you absolutely need a mora, an opinel, or one of a million other perfectly serviceable small belt/pocket knives for delicate tasks, whittling, and food preparation.
