Title: Pick-resistant lock system with improved cylinder construction

Abstract: Disclosed is an improved cylinder construction for use with a lock system. The cylinder services to frustrate the use of lock picking tools, such as a tensioning device. Specifically, a pair of opposing flat regions are formed at the lower end of the cylinder. Furthermore, the key way formed within the cylinder has an opened lower end. These features make a system which is completely resistant to picking by way of traditional pick tools. Furthermore, the cylinder cannot be broken by way of a screwdriver or drill.
