My most carried knife while camping or hiking is usually a leatherman, 90% of the time and leatherman wave. Usually a mora goes with me in the car, and usually whatever normal knife I'm carrying comes along to, whether that's something traditional or modern. I'm a big backpacker starting from when I was a kid, I carried a leatherman kick for probably a decade. Nowadays I'm generally ultralight, I carried a small Opinel No.6 for many years, then a buck 112 slim select, then a mini bugout for a while. During my army days I carried a swiss army knife, along with the issued multitool. But the last 5 or so years I've been carrying the leatherman wave, with honorable mention going to a SAK pioneer and huntsman. I think a leatherman is a little on a heavy side for most people, but for me it's worth it just in case.
