Is it illegal to chop people all over the street with a kitchen knife without chopping them?

For example, hacking with a knife is a crime of injury, hacking to death is a crime of injury, and hacking to death on the spot is a crime of intentional homicide. Can it be called a crime to cut people without a knife?

Refute the answer on the first floor again: If you say so, the martial arts master can kick people's heads off with one foot. Can you keep him off the street? According to you, anyone can pick up a brick from the roadside and shoot a person. Can you keep everyone indoors? It's a joke. ...

However, I have to remind the landlord: don't be so impulsive when encountering similar things in the future, as long as you go out with a murder weapon, you will have obvious motives. If the police arrive at this time and invite everyone to the police station for questioning, then you will be passive: the police will think that you have obvious motives and are in possession of the murder weapon. If they can't arrive in time, the problem will be serious. At this time, it is not illegal ... it is possible to criticize education or even detain for a few days, but this is just speculation. I don't know what it looks like. In a word, I want to remind you not to take any kitchen knives, bricks, sticks and the like under any circumstances. There may be some unexpected events that you can't control yourself, so it's really easy to have an accident.
