The Merchandise of the Rambo series includes shirts, hats, video games, replica posters, toys, replica knives and compound bows.
Official movie reproduction knives made of real stainless steel are for sale by companies licensed to produce them by Gil Hibben and Jimmy Lile. The original movie knives were closer to the movies and were produced by United Cutlery. However, when they lost the license, Master Cutlery bought it and although their replica knives are authorized by Gil Hibben, they are not as popular with fans because they are of lower quality. The most popular knife for sale is the Rambo III Knife, which has sold over 280,000 copies. The knives are so popular with collectors and so lucrative, that other knife companies produce similar-looking knives.
