Is glass sharper than a knife?

Re: Why is broken glass often sharper than a knife? Glass is technically a liquid although it is very viscous so it does not have any defined crystal structure or faces to crack along when it breaks it exhibits what is known as a conchoidal (shell shaped or curved) fracture.
