I saw a video (no idea where it is now) where the hostess at a dinner encouraged the diners to hurry with their meal so that their knives and forks could be picked up (confiscated?) before obama arrived.
They could keep their spoons, if I remember correctly.
Personally, I wouldn’t want to get near enough to him to use any kind of tool on him.
If I saw him burst into flame, I wouldn’t p!ss on him to put it out.
