I might have a fixed blade on my hip or in my pack. I always have a folder in my pocket, usually either the Victorinox Farmer or OHT (One Hand Trekker).

For camp chores I have a new appreciation for the Gransfors Bruks Small Forest Axe. I took it out this weekend and it is a chopping machine. A knife is still much more versatile and if you have access to only one light-weight tool then pick a knife. To live in the life of luxury, add a small axe and saw to your gear.
