This weapon appears to the untrained eye as nothing more than a beautifully crafted lady's fan. In fact, the vanes of the fan are crafted from steel, and the ribs are needle-sharp. When first brought into melee, the wielder may attempt a Bluff check against an opponent's Sense Motive check. If the wielder wins the contest, he adds a +4 bonus to the attack roll for his first round's attack(s).
