This handmade pewter flask is made in the traditional steel-producing city of Sheffield, England. Arthur Richard Wentworth, a pewter-smith, founded the company in 1949. 
The Wentworth Pewter Pocket Flask [$69.00] is compact enough to fit in a coat pocket or a handbag, but the curved shape makes it nicely suited for the breast pocket of a sport coat. Looks especially dapper in the hands of a groomsman. The flask comes in two sizes: 4 or 6 ounce.
