The main purpose of punching a kitchen knife is to make it convenient to take it without standing and hanging it, so as not to let children accidentally get hurt when taking it.

Generally speaking, a bone-breaking knife with a small hole in the back of the knife is a bone-breaking knife. People often use bone knives to cut meat and chop bones, but in this process, the stress will be transferred to the whole back of the knife, and excessive force will lead to the damage of the knife.

At this time, drilling a small hole on the back of the tool can disperse the stress, and the round hole is helpful to release the stress and make the back of the tool bear the force evenly, thus protecting the tool and prolonging its service life.

Small hole of kitchen knife

This small hole can also be used to drain water. Before stainless steel was widely used, most tools were made of iron, which was easy to rust. Iron in rust is trivalent iron ion, which is highly oxidizing and will oxidize other substances in our body, causing harm to our health.

In addition, it should be noted that long-term use of rusty kitchen knives will affect your health, so it is best not to cook with rusty kitchen knives, and such a small hole can be used to hang kitchen knives, so that the residual water on the kitchen knives can drip down under the action of gravity to prevent the kitchen knives from oxidizing and rusting too fast.
