Olfa Spare Cutter Blades, Heavy Duty, 18mm x 100mm, Snap-Off Blades for Utility & Cutter Knives - Pack of 10

Key specs: 18mm blade width to fit standard utility knives, heavy-duty construction for tough materials, snap-off design with 8 segments for an extended sharp edge, precision-ground edges for clean cuts, a pack of 10 blades, and a safe storage box for organized, easy access.

Each pack contains 10 blades, and each blade is sized at 18mm in width and 100mm in length, designed for extended use in heavy-duty cutting tasks.

Yes. The 18mm width is the standard size for many utility and cutter knives, so these blades are designed to fit most 18mm utility knives. Always validate your knife's blade cartridge compatibility before use.

To replace the edge, locate the pre-scored faint line on the blade and snap off the spent segment along the indicated break line. Remove the old segment and rotate or snap a fresh edge into place. Always handle blades with care and use the knife’s guard when not in use.

They’re designed for heavy-duty tasks like cutting cardboard, leather, thick paper, vinyl, and plastic. The precision-ground edges help deliver clean, straight cuts with less effort.

Use a sharp edge for each cut, apply steady, even pressure, keep the blade perpendicular to the material, support the work surface to minimize deflection, and replace the edge promptly when the blade dulls to maintain accuracy.

Store the blades in the included safe storage box to prevent accidental contact. For disposal, place used blades in a designated sharps container or a metal/rigid container designed for blade disposal to prevent injury.

Common use cases include crafts, packaging and box opening, trimming vinyl or leather edges, model making, and any project requiring durable, long-lasting cutting edges without frequent sharpening.

Yes. Always wear eye protection when cutting, keep fingers away from the blade path, cut away from your body, replace blades with the knife guard engaged, and store blades securely in the provided case when not in use.

With a pack of 10 blades and a snap-off design that eliminates sharpening, you get multiple sharp edges over time, reducing downtime and replacement costs. The heavy-duty construction is designed for repeated use on tough materials, making them cost-effective for ongoing projects.
