These thick leather gauntlets sport real dragon’s teeth for studs.

Dragonfang gauntlets function as masterwork spiked gauntlets and also grant you a +2 enhancement bonus to Strength.
In addition, three times per day, you can activate the gauntlets to treat your next melee attack against a weapon or shield as though you had the Improved Sunder feat, even if you don’t meet its prerequisites.
If you have Improved Unarmed Strike, dragonfang gauntlets allow you to overcome damage reduction with your unarmed strikes as though you were wielding a magic weapon. In this case, you deal unarmed strike damage instead of spiked gauntlet damage.

Prerequisites: Craft Wondrous Item, bull’s strength, magic weapon, shatter.
Cost to Create: 4,000 gp (plus 610 gp for base item), 320 XP, 8 days.
