Why is it so difficult to buy knives in supermarkets now?

It is not difficult to buy knives in the supermarket, but there may be some restrictions.

Due to the change of social security situation in recent years and the consideration of consumer safety, many supermarkets have taken restrictive measures on the sale of knives. These measures may include limiting the types, sizes and quantities of tools sold. In addition, some supermarkets may require consumers to provide identification or conduct other security checks to ensure that the purchased knives will not be used for illegal purposes.

In addition, in order to prevent knives from being used for malicious acts, some cities or regions may impose specific restrictions and regulations on the sale and possession of knives.

Therefore, if you want to buy knives in the supermarket, I suggest you check the relevant local regulations and the internal policies of the supermarket in order to understand the specific situation and abide by the regulations. If you encounter any problems or restrictions, you can contact the supermarket staff or local authorities for more information.
