Armorbane Gauntlets

(By the way, thanks Aaron/Kroz for the idea.)

These regular looking claws or iron gloves have the Armorbane spell cast on them. Thus, they tear apart armor like it's not there! More as if it's some sort of clay or Jello than if it's steel, kevlar and titanium. Of course, blades, guns, and so on can also get this enchantment, but this is the most popular mass-marketed item.

Cost: 300,000 GP.
