Cardboard Utility Knife Donau 18 mm blade, large plastic handle

Donau cardboard utility knife with an 18 mm blade and large plastic handle is designed for routine cutting of cardboard, paper and light packaging materials. The tool features a replaceable 18 mm blade and an ergonomic plastic body that provides a secure grip during repetitive tasks. Its compact size and simple mechanism make it suitable for warehouse, shipping and general packaging work where a reliable manual cutter is required.

Advantages

The large plastic handle offers enhanced hand support and reduced fatigue during prolonged use. A replaceable 18 mm blade ensures consistent cutting performance and easy maintenance without replacing the entire tool. The construction is lightweight yet durable, allowing controlled cutting of corrugated cardboard, wrapping and lightboard materials. The simple blade-change mechanism minimizes downtime and keeps the cutter ready for frequent tasks.

Suitable for

• Cutting corrugated cardboard and carton sheets
• Opening shipping boxes and packages
• Trimming paper and lightboard materials
• General warehouse and packing station tasks

Key specifications

• Blade width: 18 mm (replaceable)
• Handle type: large ergonomic plastic handle for two-handed or single-handed use
• Primary materials: plastic handle with metal blade
• Intended use: manual cutting of cardboard, paper and light packaging materials
• Weight category: lightweight for ease of handling

How to use

Hold the cutter by the large plastic handle with a firm grip and align the blade with the cutting line. Apply steady, controlled pressure and draw the blade through the material in a single pass or multiple light passes depending on material thickness. Replace the blade when cutting becomes less effective: open the blade compartment according to the tool’s mechanism, remove the spent segment or blade and install a new 18 mm blade, then secure the compartment before use. Observe safe cutting angles and keep fingers clear of the blade path.

Usage recommendations

Use the knife on a stable surface and cut away from your body. For thicker or heavily reinforced packaging, make several shallow passes instead of a single forceful cut to maintain control and extend blade life. Store the cutter with the blade retracted or covered when not in use.
