The Gum Fuddy originated in WWII when there was a shortage of traditional handle materials. Case product developers came upon a hard black synthetic material which demonstrated high durability, strength and overall appeal. A special jigging pattern was applied to the material surface to create the unique Rough Black knife handle slabs. The knives that resulted became known as Gum Fuddy knives at Case, a nickname quickly adopted by the consumer market as sales of Rough Black knives grew. Now it's back.
