## Item description

This is the description text Roblox carries for the item, quoted verbatim:

> In the aftermath of World War VII, isolated pockets of human survivors raided ruined government labs, looking specifically for these weapons. The Spec X program had been accelerated in the late 2120s as the prospect of an all out metahuman vs. machine war became increasingly likely. Prized for their ability to slice through viridian steel exoskeletons, the US was determined to find a substitute for the pure diamond required for the manufacture of the Beta models. Sapphire, while still exorbitantly expensive, allowed the army to produce blades that were 95% as effective as the Betas, at only 20% the cost.
