The gunstock pattern is an unusual, attractive and collectible pocket knife. They are typically smaller jack knives whose frame resembles the stock of a rifle. The bottom side of the frame is flat but the top side has a swell that does not taper towards the non blade end. Collectible gunstock jack knives have been made by many companies such as Case, Camillus, Uslter, Schatt & Morgan and more!
