Where should I put the knife my son came back from Tibet at home?

It's best not to hide the knife where you can see it at a glance. Small Tibetan Dao is wrapped in red cloth and put out of the reach of children.

In fact, there is no specific statement on how to put it.

The proliferation of fake Tibetan knives in Tibet. If you are not sure whether the Tibetan Dao you bought is true or false, don't put it in the living room or bedroom rashly, because the residual chemical components will cause physical damage.

In addition, if you are sure it is an authentic Tibetan Dao, please don't be superstitious about what others say. What Tibetan Dao is used to ward off evil spirits is completely nonsense. Just put it in the drawer after maintenance.
