Utility knife WEDO 78 618 — snap-off blade, 40 mm cutting width, steel body, 170 mm length

WEDO 78 618 is a utility snap-off blade knife featuring a 40 mm cutting width, a steel body and a total length of 170 mm. The tool is designed for controlled cutting of cardboard, packaging materials, carpet and similar sheet-type materials. Its replaceable segmented blade allows quick renewal of the cutting edge by snapping off worn segments, while the steel housing provides structural stability for repetitive cutting tasks.

Advantages

The snap-off blade design ensures consistent sharpness without the need for complex blade changes, reducing downtime during repetitive tasks. The 40 mm cutting width offers a broader cutting path compared with standard smaller blades, useful for thicker or wider materials. A steel body delivers increased rigidity and wear resistance compared with plastic-bodied models, and the compact 170 mm overall length balances reach and maneuverability for both detailed and straight-line cuts.

Suitable for

• Cutting corrugated and flat cardboard
• Opening and trimming packaging and shrink wrap
• Cutting carpet, linoleum and floor coverings
• Workshop and warehouse general-purpose cutting tasks
• Home DIY and renovation tasks requiring a robust utility knife

Key specifications

• Cutting width: 40 mm
• Blade type: snap-off segmented blade
• Body material: steel
• Overall length: 170 mm
• Blade renewal: segment snapping for quick edge refresh

How to use

Hold the knife with a firm grip on the steel body and align the blade with the cutting line. Apply steady, even pressure and use multiple light passes rather than a single heavy cut when working with thick or dense materials. To renew the cutting edge, extend the blade to expose a scored segment, then snap off the worn segment using appropriate pliers or the built-in breaker if available. Retract the blade fully and secure any locking mechanism when the knife is not in use.

Usage recommendations

For safe operation, always cut away from the body, wear cut-resistant gloves when handling heavy or thick materials, and dispose of used blade segments in a puncture-resistant container. Keep the knife dry and free from corrosive substances to maintain the steel body and blade condition. Use replacement blades compatible with 40 mm snap-off segmented systems to ensure correct fit and performance.
