gems were put in the hilts for decorations (the blade morphed to accept them) the investiture in the gems allowed for the binding of the blade.

Could you wrap the hilt in steel and have a feruchemist invest it and then have a steel mind ready to go? would that invested steel vanish like the gems did? (also assume the user is a steel runner feruchemist or that it’s scadrian tech that allows anyone to use the steel mind)

Maybe everybody else realized this already, it I finally figured out why Notum was attacked in book four.

At the end of book four when Dalinar and the gang were looking through Ishar’s tent they read in the log book that the honor spent had survived 15 minutes and that they needed to capture more for further testing.

Ishar ruled in Tukar, the band of men were Tukari, they were trying to capture an honor spren.
they were sent by Ishar to capture Notum, to bring him to the physical realm.
