Politics: Is it true that one 9/11 plane was hijacked with only a butter knife?

Honestly, where did you hear that? Even if they did find a butter knife in the wreckage, what make you, or anyone else think it was used in the way you suggest? A butter knife is a common item. I'm sure many of them were found. But that doesn't mean there was a hijacker wielding one like a samourai sword.
