About 1 in every 100 times I pass through a checkpoint, they ask me to remove my small umbrella from my carry-on and spread it out on a tray so they can xray it again... I asked once and they only do it if there is a high metal concentration (eg all of the metal parts of the small umbrella folded close to each other), and it's remotely possible that there could be a knife or syringe etc concealed in there... when they have a clearer view on the xray, they don't need to ask for it to be separated.
