In-game description Edit
|“|| Belt of the Skillful Blade|
A blacksmith in Cormyr is responsible for designing this item. Say'an Keenedge was renowned for designing the sharpest, best balanced, and most beautiful blades in the country. She was also a bit of a hothead and grew furious when she saw less-skilled fighters wielding her weapons. For her finest work she handed out one of these belts free with purchase, in order that her weapons never be mishandled.
