"Thats kind of weird. How do you hold things to cut them?"
I don't cut things. I avoid spaghetti. There are so many nice pastas that are easier to eat. Meat when hiking is always pre-cut and dried in the meal before we leave home. Rice, potatoes, burritos, pasta, cereal, oats with small pieces if veggies and meat can all be eaten with a spoon.
At home, if I have a piece of food too big to pick up with a spoon (eg meat, corn on the cob), I just pick it up with my fingers and tear it with my teeth. The only exception is some leafy salads where I might deploy a fork, but we never have leafy salads on the trail.
