In a society, where everything is made up of glass, everything would break rather easily. Things like swords and mallets couldn't function in such a world. As to still have something o work with, I thought about utilizing the sharp edges of glass for cutting, instead of slamming.
A sword, for example, would become something like an Aztec macuahuitl. Here a wooden club is equipped with several obsidian blades, creating a very effective weapon. The same basic principle should also work for other cutting tools, like axes and saws. When it comes to mining, however, things get difficult.
Striking and prying chunks out of a stone wall will simply break any glass tool, solid or otherwise. Even a glass-tipped pick will be no more useful than anything else.
So, I thought about it and came up with the concept of a chisel. Instead of striking a surface and trying to pull pieces out of it, the chisel would be placed on it and then grind itself in, creating cracks which allow for the removal of rocks.
Now my question: Would this be possible, or is the stone too hard for the glass to burrow into? does the chisel break when being hammered inside, or does its cutting edge do all the work? Also, how well would a spade work in this context? Please help me! Thanks!
