Paper Cutter Knives & Guillotine Blades for Challenge, MBM Triumph & Horizon Cutters

Replacement blades for commercial paper cutters

Mid-State Litho supplies paper cutter knives and replacement guillotine blades for commercial cutting equipment from Challenge, MBM Triumph and Standard Horizon. We carry carbon steel, high-speed steel (HSS) and inlaid HSS options for a wide range of cutter models.

Because we also sell and service the paper cutters themselves, we can help match the right blade by model, hole pattern, material and production demand. Mid-State Litho also carries Perfecta cutting systems.

How to choose the right replacement knife

• Match your exact cutter model: blade length and hole pattern must match precisely.
• Choose blade material by workload: carbon steel for general use, HSS for production, inlaid HSS for long edge life on coated and laminated stock.
• Consider your stock mix: coated, laminated or synthetic sheets will dull standard blades faster.
• Look for cut-quality issues: rough edges, fiber pull, stack draw and uneven cuts often point to a dull knife. A worn cutting stick produces the same symptoms, so check both.

Not sure what fits your machine? Contact our parts team with your model and serial number. If your blade issue points to a larger machine problem, we also offer complete guillotine paper cutters. These include hydraulic guillotine cutters and programmable paper cutters.
