Impossible Blade

 is a Melee Medium Artifact weapon in Torment: Tides of Numenera.

Description
One glance at this weapon serves as an explanation of its name, as the blade is of an impossible thinness. A transdimensional energy field generated by a device in its short handle maintains the blade's structural integrity, and as such, the blade can't be used when this field is not powered, as it would shatter on the slightest impact.
