Crabb still specifically hands over her own piece wrapped in a handkerchief because she agrees with Ylva re: not touching the metal with your bare skin if you can help it. Though if Valdis is going to do some magic crap who knows maybe she'll just go ahead and touch it anyway...

"Can't call this one a finger," she's not even sure how they deduced that about the other one, "but it looks like it's the same thing. So..."

Two pieces to sense stuff off is better than one? Probably?
