How about bic style razors?
For the longest time they took away disposable safety razors. How are you going to hijack a plane with a bic razor? "Infidel! I will cut your throat! Hold still now, this will take a while..."
The no fly list is another joke. Suspected terrorists aren't put on the no fly list because they don't want them to know they are being watched. So, the million people (Yes, a million people!) on the no fly list are not suspected of being terrorists. So, why are they on the list? Why is there a list at all?
