Utility knife Topex with snap-off blade, 18 mm, metal rail

Topex utility knife with an 18 mm snap-off blade and metal rail is a handheld cutting tool intended for precise trimming of paper, cardboard, plastic and similar materials. The segmented blade design allows quick restoration of a sharp edge by snapping off worn segments, while the metal rail provides stable blade guidance and increased durability compared with plastic-bodied models. The compact form and straightforward mechanism make this tool suitable for workshop, packaging, craft and general repair tasks that require a replaceable, controllable cutting edge.

Advantages

The metal rail ensures smooth, accurate blade movement and prolongs the lifetime of the body under frequent use. The 18 mm segmented blade offers a balance between cutting width and control, enabling straight cuts and access to tighter areas. The snap-off system reduces downtime because dull segments can be removed quickly without tools. The simple locking mechanism secures the blade at the chosen extension for safer operation.

Suitable for

• Cutting packaging materials and cardboard
• Trimming paper, vinyl and thin plastics
• Workshop tasks and light repair work
• Crafting, model making and hobby projects

Key specifications

• Blade type: segmented snap-off blade, 18 mm width
• Body: handheld design with metal blade rail for guidance
• Blade change: replaceable segments with snap-off feature
• Locking: manual blade locking mechanism to fix extension
• Typical uses: general cutting of paper, cardboard, plastic and similar materials

How to use

Slide the blade out to the required cutting length and engage the locking mechanism to fix it in place. Make controlled cuts with the blade angled appropriately to the material surface, applying steady, even pressure. When the cutting edge becomes dull, extend the blade slightly, score and snap off the used segment according to the blade’s break lines, then retract to the safe position or set the next segment at the required length. For full blade replacement, open the handle as permitted by the model design and insert a new 18 mm segmented blade, ensuring it seats correctly in the metal rail.

Usage recommendations

Work on a stable surface and cut away from your body. Use protective gloves and eye protection when snapping blade segments. Store the knife with the blade retracted and keep spare segmented blades in a protective packet to avoid injury.
