Replaceable Snap-off Blades 18 mm, MEGA 10-pack (model 31018H)

Set of 10 replaceable snap-off blades MEGA 31018H, each 18 mm wide, designed for use in compatible retractable and break-off blade utility knives. The blades are segmented to allow fast restoration of a fresh cutting edge by snapping off a worn segment. Intended for general cutting tasks including paper, cardboard, plastic film and other light materials, the set provides spare blades for uninterrupted work and reduces downtime when a blade becomes dull.

Advantages

These 18 mm snap-off blades offer a balance of cutting precision and user convenience. Segmented design allows quick blade renewal without tools; the 18 mm width provides stable guidance in most utility knife models that accept snap-off blades. The set of ten ensures availability of replacements, reducing the need to stop work to resharpen or replace a full blade. Made to fit a wide range of retractable cutters, the blades deliver consistent cutting performance across routine tasks.

How to use

Insert a blade into a compatible retractable utility knife following the knife manufacturer's instructions, ensuring the segment grooves align with the knife's blade stop. Use the cutter with a steady, controlled motion and replace or snap off segments when the edge becomes dull. To snap off a used segment, extend the blade to the appropriate notch, hold the blade with protective pliers or the knife's built-in breaker, and break the segment away along the scored line. Dispose of broken segments safely in a sharps container or by wrapping before discarding.

Usage recommendations

For safe handling, always retract the blade when not in use, wear cut-resistant gloves when changing segments, and store spare blades in their original packaging to prevent accidental contact. Choose the 18 mm blade width if your utility knife accepts standard snap-off blades and if you need a stable blade for general cutting tasks.
