The Duo is the utensil set for people who want a real fork and a real spoon on the go. The Duo utensils are each long enough to be used separately and both are optimized for what they need to do. The tools snap together in an ultra-compact nested mode. They can also be re-connected end-to-end for eating out of rehydrated food bags, deep to-go containers, etc. The locking mechanism has been carefully designed for easy cleaning even when you're miles from the nearest dishwasher.
