So I've been wondering why the people of Roshar call Shardblades and plate it the way they do? The speak of having "shards", but I haven't found out why they do this. Who named them like this, and was this person aware of the Shards of Adonalsium? If the language from when the Knights Radiant is no longer around, then a word like Shardblade wouldn't be the same either. So it has to be a more modern word.
Is it just a coincidence or is there an actual meaning to it related to the Shards, and if so, how?
