Under 10 grams and completes 100% of all of the things you ever actually need a knife to do while backpacking.

Will it save you from a bear attack? Nope. And that doesn't really happen.
Will it skin a rabbit? Nope. You're backpacking not playing survival games.
Will it chop a carrot? Nope. You're backpacking, this isn't the place to practice culinary arts.
Will it cut rope? Nope. What are you doing with that rope, anyway?
Will it cut cheese? Yes! Now we're talking!
