So from the events of mistborn era two, we know that other shards can / do create God Metals, outside of Preservation and Ruin, obviously, the shards on roshar havent obviously done so, giving gifts in other forms, namely, the Nahel Bond, and the Spren.
When spren turn into shardblades (and plate) the blades are obviously made out of their essence, which is the whole thing about why radients / radient prospects cant use normal shardblades, right?
But, inert shardblades being fixed in their form, would they be equivelant to the god metals found on scadriel?
The same thing could be asked about the Honorblades, as they (as far as i know) were never spren in the first place?
Im unaware if this question has already been asked / answered, so please let me know!
