Can I take {insert sharp object here} on an airplane?

Since Sept 11, there are security measures in place for your own protection and everyone else around you.

I don't care that they are antique Derringers and a trigger lock cannot be placed on them, you will then dismantle them and lock the parts separately in two separately locked boxes. I don't care that they have never been fired.

No sir, I don't care if they are ceremonial knives, they will be in a locked box that you cannot see through. No sir, I understand that they are used for teaching but they must be in a locked box. No sir, duct tape will not suffice.

No, ma'am, culinary knives must be in a secured locked box and no, they may not be carry-on. I understand that they are expensive, you will be required to sign a release form for our liability, however, you cannot take them as carry-on.

Yes ma'am, you can now bring knitting needles.
