If you find a knife, the best thing to do is to leave it where you found it and notify a nearby adult. If there is no adult around, or if you are unable to safely leave the knife where you found it, then you can take it with you, but only if it is safe to do so. Once you have taken possession of the knife, ensure that it is kept out of reach of children and away from areas where people could trip over it. If possible, put the knife in a container or wrap it in something before storing it safely until you can dispose of it properly.
