Ok, so it is not exactly a 3-in-1 utensil. But a combination of these rather long fork and knife (10.25″ each) work as a pair of chopsticks as well! To make life even simpler, the top of the chopsticks are even textured for better gripping as well.
“ForkChops 3-in-1 Eating Utensils are three of the most common utensils all mashed into one. You get a fork. You get a knife. You even get a pair of chopsticks!” They are made of made of food-safe polystyrene, and are reusable and dishwasher safe.
Price? $6 (for both pieces)
