Note: There was no way for Blanche to know at the time, but she was lucky that the fork and the gun she manipulated contained no pure iron. As anyone today knows, iron has a destabilizing effect on phase fields. This is not a big problem for practising mentats, as they can often find ways around directly manipulating iron objects, especially since so few exist in our modern world, but a currently out-of-phase person would be lethally destabilized by any contact with unalloyed iron.
