I don't think that Obsidian would stand up to any attacks, or even if the weapons themselves would survive being USED to attack. I think that it is most likeley a metal alloy.

It could also be stone, if we think about it. Earth dust is a possiblility, and if you melt dirt and solidify it, you get stone. This would be a more likely material, as obsidian is glass.
