There isn't a specific age at which people typically stop keeping knives in their homes. The presence of knives in a household depends on various factors, including cultural norms, personal preferences, and individual circumstances.
In many cultures, knives are essential kitchen tools and are commonly found in homes regardless of age. People of all ages continue to use and keep knives for cooking and other practical purposes. However, some households may take extra precautions when there are young children or elderly individuals with certain health conditions that make knife handling riskier.
Instead of focusing on an age limit, it is more important to emphasize responsible knife ownership and safety practices in households. Educating individuals on proper knife handling, storage, and safety measures is crucial to prevent accidents and ensure that knives remain useful tools without unnecessary risks.
