Is the design of the knife patented?

It is indeed patented, but the domestic imitation knife only imitates the shape of the original knife. The real value of a knife lies in its material and its mechanical principle. A good knife is not only simple enough to be beautiful and sharp enough, but more importantly, it has toughness, wear resistance and corrosion resistance, cherishes the materials used for making it, and uses ergonomics. In this way, imitations will basically not affect the sales of genuine products, because the quality of imitations is mostly poor. If it is copied by a big factory, patents can be used as weapons.
