Paper Cutter Knives & Guillotine Blades | Challenge, MBM, Horizon

Replacement knives for Challenge, MBM Triumph, and Horizon cutters — with expert fit guidance, blade material options, and support from a dealer that also sells and services the machines.

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 tungsten carbide 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 demands.

Carbon Steel

Affordable, dependable blades for standard paper stocks and moderate daily cutting volumes.

High-Speed Steel (HSS)

Longer edge life for coated stocks, laminated sheets, and higher-volume production environments.

Tungsten Carbide

Premium blade option for abrasive materials, demanding applications, and maximum service life.

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, carbide for extreme wear resistance
  • 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

Frequently Asked Questions

How do I know which replacement knife fits my paper cutter?

Match the blade to your cutter model, blade length, and hole pattern. If you're unsure, send us your brand, model, and serial number and we can confirm the correct replacement knife.

What is the difference between carbon steel, HSS, and carbide blades?

Carbon steel is the most economical for standard work. HSS lasts longer in production and on coated stocks. Tungsten carbide offers the longest life for abrasive or specialty materials.

How often should I replace a guillotine blade?

It depends on cutting volume, stock type, and operator use. Rough edges, fiber pull, visible nicks, or stack draw are common signs that a blade needs sharpening or replacement.

Should I use OEM or aftermarket replacement knives?

OEM or OEM-spec knives are the safer choice for fit, grind angle, and machine performance. Poor-fit aftermarket blades can affect cut quality and machine wear.

Do you offer installation or service support?

Yes. Mid-State Litho supports cutter service, blade installation assistance, and related technical support throughout Michigan and the Great Lakes region.
