Deathclaw gauntlet

The deathclaw gauntlet is the hand of a deathclaw strapped to the characters arm to create a weapon. This weapon is not available for purchase or construction in Fallout: New Vegas.

It does devastating damage, combined with a high critical hit rate and can instantly cripple a limb with a charged hit. Schematics can be found in Fallout 3 at any Random Location A point, as there will be a Wasteland wanderer dead, and a deathclaw nearby. He could be found alive, though it is rare. Another copy of the schematic is given to you by Bannon from Rivet City for dealing with Seagrave. After entering the Pitt as a slave, you can battle your way out of the arena to freedom. One of the Bear Brothers drops a Deathclaw Gauntlet on his body.

Building
To build a Deathclaw guantlet, you need a Deathclaw hand, a medical brace, a leather belt, and 1 Wonderglue.
 * See Schematics - deathclaw gauntlet.

Presumeably, the medical brace is what goes around your player's arm, the leather belt connecting the medical brace and the Deathclaw hand, and the wonderglue helps hold it all firmly together.

Appearances
Deathclaw hands appear in Fallout 3 and Fallout: New Vegas.
