Maxwell Slitter Industries is among the largest manufacturers and suppliers of replacement rotary slitter knives for both slitting and side trimming. As with all of our products, we manufacture our replacement slitter knives from the best alloy tool steels and engineer them for your unique application.

Each knife we manufacture is hardened and tempered to ensure uniform blade hardness; this results in decreased regrind cycles, longer runs, and higher-quality slit edges. We use a variety of standard and unique alloy grades to manufacture our slitter blades. All of our blades are manufactured from forged steel and heat-treated to achieve the proper grain structure and optimal mechanical properties necessary to meet your slitting needs.
