About Cumberland Knives
Precision Engineered. Built to Last.
Cumberland Knives is a manufacturer of industrial cutting knives purpose-built for the recycling industry, designed to perform in the most demanding shredding and granulation applications.
Our Focus
Cumberland Knives was built around a single principle: recycling operations deserve cutting knives that are engineered specifically for their equipment and materials, not adapted from general-purpose blades. Every knife we manufacture is designed to meet the precise tolerances, steel grades, and geometry required for consistent performance in low speed granulators, central granulators, heavy duty granulators, multi-purpose shredders, pipe and profile shredders, and combination shredder and granulator systems.
What Sets Cumberland Apart
