Good question. I wondered if anyone would notice that. I carry two spoons because....First of all, the second spoon is a very lightweight plastic spoon (like you might get at MacDonald's) that is insignificant in weight.* The main spoon is a better Lexan or similar spoon. Quite often, in the past, when traveling with a small group someone has forgotten or lost their spoon and it was nice to have one to give them. I keep one of the spoons in my cook set and the other in my food bag. Often times I temporarily misplace my spoon and use the second until I happen to run across the other in my pack somewhere.

*I know to the UL backpacker nothing is insignificant, but the lightweight spoon weighs one gram (0.035274 ounce) and I could spit and loose that much weight!
