ABSTRACT:
A knife system with symmetrical "U"-section swing handles has a removable, integral accessory detachably force fitted to it to lock the handles together in blade-exposed or use-position, and to serve as a scraper, a pair of offset screwdrivers providing finger relief, and a grip improver. The force-fit may advantageously include three types of engagement between the lock and the handles for maximum security. The lock may be easily installed by tapping it with or against something; removal is difficult except by appropriately directed tapping.
