They are sharp, so the damage is high. They should be scarce and costly, but that's no different from other high end materials and armour penetration separate from damage?
I had mental sexytimes by imagining glass weapon class with very little degradation and high damage versus unarmored foes, high speed and lowered energy cost due to weight and balance, very high wear penalties and no penetration for hitting moderately armored foes or a wall or wooden post, molded into suitable forms only like dagger, broad arrowhead(with high chance of nonrecovery upon miss), short stabbing sword, longsword/scimitar at most and being the rarest and costliest with not much damage increase, combat effectiveness and damage rolls favoring high dex characters rather than high strength, with increased notoriety/depostition penalties if displayed in full view due to stigma associated with such
