Space and time can be described as fabric, so what better way to manipulate it than by cutting it? Usually a bladed weapon or claws are used for such a purpose, sometimes noted to be an Absurdly Sharp Blade, but this could be done with any natural or artificial cutting implement.

The Full-Contact Magic version of Thinking Up Portals. A subtrope of Interdimensional Travel Device. Compare with Teleport Gun. Not to be confused with Portal Cut.

She has the unique power to open gateways to select people she has a bond with, mostly family members.

Problem is that this breaks the universe on the other end in a way that makes it uninhabitable or even erases it altogether as is the case in the last test log. The powers that be in the multiverse send the Foundation a signed order to stop using it.
