The real purpose of the small round holes on a kitchen knife is to reduce the weight of the knife and strengthen it.

A kitchen knife is a kitchen utensil that is used to cut ingredients. In the process of use, the kitchen knife needs to withstand a certain amount of pressure and friction, so it needs to have a certain degree of strength and stability. And in order to make the kitchen knife sharper, the blade needs to be as light as possible to reduce fatigue when using it. In order to achieve these two purposes, some kitchen knife manufacturers put a small round hole in the body of the knife. This small round hole can effectively reduce the weight of the knife body, as some metal bodies can have excess metal material removed after the hole is punched.

At the same time, the small round hole also enhances the strength of the knife. When impacted by external forces, the knife body can better disperse the impact force due to the presence of small round holes, thus increasing the knife's impact resistance. In addition, some kitchen knife manufacturers also enhance the strength and stability of their knives by changing the shape, material and heat treatment process of the knife body. These measures can be used in combination with small round holes to achieve better results.
