What is the significance of prohibiting students from carrying controlled knives?

The hazards of students carrying controlled knives are as follows: First, it is a crime to hurt themselves or others because of playing. Second, students carrying controlled knives are easy to be used by criminals and become criminal tools, endangering public safety. Third, because carrying controlled knives encourages students to be brave and win, once there is a conflict with classmates, the controlled knives carried with them are likely to become tools for committing crimes. It is necessary to prevent minors from committing crimes or injuries to prohibit students from carrying controlled knives.

In order to effectively protect the personal safety of teachers and students, maintain the normal education and teaching order of the school, and effectively prevent all kinds of injuries on campus, and implement the requirements of the Notice of the Ministry of Education and the Ministry of Public Security on Prohibiting Carrying Dangerous Goods such as Controlled Knives into the Campus, recently, our school launched a special rectification campaign with the theme of "life first, safety first".

Tool is a tool used for cutting in mechanical manufacturing, also known as cutting tool. Most knives are used by machines, but some people use them manually. Because the tools used in mechanical manufacturing are basically used to cut metal materials, the word "tool" is usually understood as a metal cutting tool. Tools for cutting wood are called woodworking tools. There is also a special type of tool used in geological exploration, drilling and mine drilling, which is called mine tool.
