A spork or a foon is a hybrid form of cutlery taking the form of a spoon-like shallow scoop with three or four fork tines. Spork-like utensils, such as the terrapin fork or ice cream fork, have been manufactured since the late 1800s; patents for spork-like designs date back to at least 1874, and the word "spork" was registered as a trademark in the US and the UK decades later. They are used by fast food restaurants, schools, prisons, the military, and backpackers. The spork is a portmanteau word combining spoon and fork. Similarly, the word foon is a blend of fork and spoon. The word "spork" appeared in the 1909 supplement to the Century Dictionary, where it was described as a trade name and "a ''portmanteau-word'' applied to a long, slender spoon having, at the end of the bowl, projections resembling the tines of a fork".
