MBM Replacement Blades

Bi-metallic blades combine two metal types to extend wear resistance significantly, with some options here rated to last 3 to 5 times longer than a standard single-metal blade under regular use. This matters most for shops cutting daily, high-volume stacks, where a standard blade would need much more frequent sharpening or replacement. For occasional, lower-volume cutting, a standard blade is a reasonable and more economical choice.

Yes, this selection specifically includes hard-to-find and discontinued model blades alongside current production models, so an older Kutrimmer or Triumph unit isn't necessarily out of luck. Confirm your model number carefully when searching, since older machines sometimes share a blade design with a newer successor model even if the machine name has changed.

Several Kutrimmer replacement kits here include both top and bottom blades together as a complete set, while other listings are for a single blade only. Full kit versus single-blade listings are labeled separately within paper cutter replacement blades, so check the specific product title before adding to cart rather than assuming a listing includes both pieces.

Look for visible nicks, a bent edge, or consistently ragged cuts that persist even after clearing paper dust and debris from the cutting area. Minor dulling can sometimes be corrected with professional sharpening, but structural damage like a bent or chipped edge won't be fixed by sharpening alone. If your shop runs a cutter or trimmer daily for high-volume work, expect to inspect blade condition more frequently than a lighter-use office setup would need to.
