The sharpest knife in existence is useless...because it is obviously not being used.
That said, obsidian shards are SUPER sharp and can be used as knives, I guarantee there are many people out there with shards of obsidian that have super-fine cutting edges.

Some are, but they're only good for like 5 to 10 cuts then they're useless.
