Knife Fiskars CarbonMax 18 mm with snap-off blade and metal body

The Fiskars CarbonMax 18 mm utility knife with a snap-off blade and metal body is a compact cutting tool intended for precise, repeatable cuts in a variety of materials. With an 18 mm segmented blade that can be snapped to expose a new sharp edge, this knife balances cutting performance and serviceability. The metal body improves durability and provides a stable, controlled grip for tasks ranging from packaging to workshop use.

Advantages

The knife offers consistent sharpness through its replaceable snap-off blade design and maintains blade stability with a rigid metal housing. Its compact form factor supports controlled cutting motions and accurate scoring on cardboard, film, carpet and similar materials. An integrated blade retraction mechanism enhances safety when the knife is not in use, while the overall construction is aimed at longer service life compared with typical plastic-handled cutters.

Suitable for

• Cutting and scoring cardboard and corrugated boxes
• Trimming plastic film, adhesive tape and packaging materials
• Cutting thin flooring materials and carpet trims
• Hobby and DIY projects requiring controlled straight cuts
• Workshop and warehouse tasks that demand repeatable, precise cuts

Key specifications

• Blade type: 18 mm segmented snap-off blade for stepwise renewal of the cutting edge
• Body material: metal housing for enhanced durability and blade stability
• Blade change: replaceable segmented blade compatible with standard 18 mm snap-off units
• Safety feature: retractable blade mechanism for secure storage when not in use
• Intended use: manual cutting tool for thin to medium-thickness sheet materials

How to use

Extend the blade to the desired length using the slider or release mechanism, position the blade along the cut line, and apply steady pressure while guiding the knife to achieve a controlled cut. When the cutting edge becomes dull, snap off the used blade segment along the scored break point to expose a fresh edge, or replace the blade entirely following the manufacturer’s fitting method. Retract the blade fully into the body and engage the safety position when the tool is not in use or during transport.

Usage recommendations

For safe and efficient operation, use a straight cutting motion and firm support for the workpiece. Wear cut-resistant gloves when handling the blade during replacement, snap segments away from your body, and store the knife with the blade retracted. Use appropriate replacement 18 mm segmented blades to maintain cutting performance.
