If the "crystal" is really glass, then its internal structure isn't terribly well organized-- it's amorphous so it doesn't have a definite cleavage plane, but that just means that when it's whacked, the pieces that come off tend to be curved rather than straight. (The same thing is true of "cryptocrystalline" materials, which are sort of glommed together from a lot of individual crystals that're randomly aligned and teeny enough that they might as well be amorphous-- I think flint works that way.)

Supposedly, certain rare types of jade are nearly crystal-clear and colorless; those would make pretty nasty weapons, since iirc jade has a sort of "felted" internal structure with flat plates interwoven with each other, making it extremely resilient. (There are anecdotes that in the big 1906 earthquake out here, one collector of Asian artifacts lost all of the ceramics when they smashed off their shelves onto the floor-- but everything made of jade just *bounced*.) However, I don't think jade fits terribly well into Cooper's idiom in this series.
