Shardblade Hemalurgy

[Gasper]

Would it be possible to use a shardblade as a hemalurgic spike? The coppermind says that the shardblades are a godmetal and another godmetal works as a spike (atium), so logically, it should be able to work as a spike. What would that do to the spren and the blade wielder?

Supposing that a skilled Hemalurgist got hold of some a Shardblade or some Shardplate, how would he best use it assuming that the best way isn't to put it on and kill people with it.

That's probably the best way, to put it on and kill people with it. I'm not sure why a Hemalurgist would want one more than anyone else would because the metal is already Invested which means its not useful to him.

(Relevant bit) 

It will not work as a spike 

[Oversleep]

It wouldn't work (or at least would be really hard to do) as Shardblades are already Invested (heavily) and so it would be hard to use one as a Hemalurgic spike.

That makes sense

If you try to stab someone with it, it just fuzzes right through them and they die.

Try to steal a piece of soul with a weapon Who destroy Souls...It can't be' really likely.

Of course there is also the "already mostly full" argument (don't consider the Atium in that as It's not so Invested).

 

Let's say It's mostly impossibile to use a Blade as Spike
