The Creature Claw is rarity 98, but I've never seen it in the Weapons Warehouse or any of the other shops. Does anyone know what shop this item is in?

SubetaLodge has it listed as stocking at the Graveyard Shop, which is closed. I don't know if it was changed to another shop (my money would be on the Weapons Wearhouse shop) or if there was an error.
