In the UK, and I suspect elsewhere, pub glasses are manufactured to indicate their age as they're meant to be replaced regularly. Often in pubs you can see they've far outlived their proper life, if you know what to look for, and are covered in etches from repeated washes. Clearly glasses last a long time, I don't think smashing is the kind of issue they're making it out to be.
These hardened glasses are sharper when they smash. They tend to smash after a few drops, but more drops than normal glasses.
They solve a historical problem from East Germany: lack of resources to make glass, which is no longer a problem. Normal glasses are recyclable. EDIT: No apparently they are not, so maybe that's useful?
