Deathclaw Gauntlet (Fallout 3)

Exactly as the name says, the Deathclaw Gauntlet is an unarmed weapon that is made out of a Deathclaw's fore arm and fist. Wonderglue, Leather Belt, Medical Brace, Deathclaw Hand and the Schematic are needed to make it.

You can get this schematic by doing the side quest given to you by the Armor Seller in Rivet City. The schematic can also be found in random locations on a dead wastelander (usually around Deathclaw-infested areas), and in a campground in the far southwest of the map, within a trailer.

The best possible way to 100% obtain the weapon early in the game is to head to F.Scott Key Trail & Campground. If you head to Ten Penny Tower (location is put on your map after talking to Mr. Burke in Megaton) then keep heading west until you come to the Dunwich Building, F.Scott Key Trail & Campground is just to the north and slightly west. If you come to the "end of the world" south or west, you've gone too far. The schematic is located in a trailer usually guarded by a Deathclaw. This makes it the perfect area to get this weapon early on. Not only do you get the schematic, but you get the Deathclaw Hand which is hard to get early.

Other rumored locations: The Schematic is rumored to be found outside the Meresti Trainyard. It's also said to be a random drop from the Raiders outside the Super Duper Mart. The Schematic may also possibly drop "randomly" elsewhere. It's been observed that quit a few enemies in random encounters can drop many different items.
