They were used a lot in aerospace and military applications.  One thing that used to appear on the surplus market was an EOD toolkit used by bomb disposal techs.  Even had a beryllium hammer.  These were wonderful tools which you might just find when clearing out old uncle Bob's estate...

Oh... where did I put that pile of junk? :->

Sounds dangerous...

I have encountered Beryllium in a field none of you mentioned, as 
material for speaker cones. Light and very rigid. Perfect for the top 
driver for horns. I recall something about high speed of sound.

Cheers,
