A backpacking knife spends most of a trip doing small, boring jobs. It slices cheese and salami, opens food bags, trims cord and cuts strips of tape and moleskin. You don't need a six-inch survival knife for any of that, and you'd be carrying every ounce of one for the whole trip.
So this page ranks small knives and multi-tools on what matters for those jobs: how much blade you get per ounce, whether the blade locks open so it can't fold onto your fingers, and how well the steel resists rust after a wet week. Multi-tools are here too, because for a lot of hikers a pair of scissors does more work than a blade.
The top of the category is Benchmade's Bugout, Spyderco and Leatherman, and those are the priciest knives here. You don't have to spend that much. A wood-handled Opinel or a Swiss Army knife covers most trips for a fraction of the money. What the Bugout really buys you is a big locking blade you can open and close with one hand, at under two ounces.
My dad and I haven't tested these eight knives ourselves, and I won't pretend we have. The order comes from each maker's published specs, AI-assisted research and what Amazon buyers say in their reviews. Every rating and review count on this page was read off its listing on the day we published.
