I have a small beryllium collection and I never pass them up when I see them. They are cool. On a side note, the best stereo speakers I have ever owned (and there have been many), are Yamaha NS1000 speakers, with, you guessed it, beryllium drivers. I understand that making the speakers was quite an engineering feat given that beryllium is very difficult to shape into speakers, but they are the best!
PS, if you'd like to swap something for your nail puller, I'd like a shot.
