cutting a copper mind

[csyandrews he/him]

As far as I am aware no metal mind has been cut or broken in the books, suggesting an incredible resiliency. If it is possible to cut a metalmind what happens to the investiture? for example, a coppermind, if it was full and then cut would the information be lost or would it be split between the two halves? I am inclined to think that it would simply be destroyed like a half shard would after sufficient trauma. what do you guys think?

What happens when you break a Hemalurgic spike or metalmind? What happens to that power?

BRANDON SANDERSON

Hemalurgic power can be split among multiple spikes and reforged, but remember that the longer a spike is outside of a person, the more the power is going to decay. Things like splitting it will decay it even further. Metalminds can also be broken and still be accessed

"Q: If someone broke a coppermind, could the feruchemist still access a fragment of the information in it from a chunk of the coppermind, or would he require that the whole thing be reformed to access any of its storage?
 
A: The information would be fragmented."

And in case you're interested

"Q: What would happen if a Feruchemist fills, for example, a tin metalmind then mixes it to make a pewter metalmind? Does the stored attribute change? Is the Investiture gone when you melt the metal? What if he just makes it into a tin metalmind again?
 
A: If you make it impure, you'll keep the investiture, but won't be able to get it out. If you make it back into the same thing, you'll be fine, and can access it normally. If you try to fill it, after changing the composition to make another viable metal, it will act a little like a computer hard drive with corrupted sectors. Some of it will work for the new investiture, but you won't be able to fill it nearly as full. (Depending on how full it was before you melted it down.)
This holds for basic uses of the metallurgic arts. Once you start playing with some of the more advanced parts of the magic, you can achieve different results, which are currently RAFO.
 
Q: So you could, for example, use electrolysis to dissolve a metalmind in water, then reverse the reaction later to get the Investiture? Or, better question, if you store investiture in one allotrope of iron, can you retrieve it if you change to a different allotrope?
 
A: I see no reason why these wouldn't work."
