For entertainment purposes, I've been reading about the Roswell incident. One account tells of a person who got his hands on some debris from the crash. He supposedly wasn't able to burn the material, or cut it with a knife that he had previously used to cut barbed wire. The thing that facinated me wasn't the exotic material from the crash but a knife made here on Earth that would cut barbed wire. If anybody knows where I can purchase one, please let me know.
My guess is that he should have cut the alien material BEFORE ruining his knife on the barbed wire.
