Utility Knife Dedra M9031 — metal 9 mm blade with safety lock for cutting paper

Dedra M9031 is a metal utility knife designed for controlled straight cuts in paper and similar thin materials. The compact metal body provides durability and steady handling, while the 9 mm replaceable blade delivers precise cutting performance. An integrated safety lock keeps the blade secured during use, reducing the risk of accidental retraction or extension and improving user control for repetitive tasks.

Advantages

The metal construction offers robust build quality and improved weight balance compared with plastic alternatives, helping to maintain a firm grip during cutting. The 9 mm blade is easy to replace and provides a sharp edge suited for precise trimming, creasing, and opening packages. The safety lock mechanism enables safe operation by fixing the blade in position and preventing unintended movement. Compact dimensions make the knife convenient to store in a desk drawer, toolbox, or craft box.

Suitable for

• Cutting paper, cardboard, and thin craft materials
• Opening envelopes and packaging
• Precision trimming for office and school projects
• Light-duty workshop and hobby tasks

Key specifications

• Body material: metal for increased durability
• Blade width: 9 mm replaceable utility blade
• Blade type: segmented/standard snap-off compatible
• Safety feature: manual blade lock to secure blade position
• Intended materials: paper, cardboard, thin plastics, and similar sheet materials

How to use

Hold the knife with a comfortable grip and extend the blade to the required length, then engage the safety lock to fix the blade in position. Position the blade against the material and apply steady, even pressure while drawing the knife along the cutting line. For controlled results, make several light passes rather than forcing a single deep cut. To replace the blade, unlock and retract the blade fully, open the knife according to the manufacturer's retention method, remove the spent segment or blade carrier, and insert a new blade following safe handling procedures.

Usage recommendations

Use the Dedra M9031 on stable surfaces and cut away from body parts. Keep fingers clear of the blade path, wear protective gloves if needed, and store the knife with the blade retracted and lock engaged. Replace blades as soon as they become dull to maintain clean cuts and reduce the need for excessive force.
