The deathclaw gauntlet is made out of a deathclaw's hand, a medical brace for extra structure, a leather belt to render the hand rigid (and as a handle for the user's hand) and wonderglue to hold it all together. Deathclaw gauntlet schematics are needed to build it. See: Schematics - deathclaw gauntlet.
