Utility knife set DNIPRO-M K-18 sliding lock with 18 mm blades, includes 4 replacement blades

DNIPRO-M K-18 is a utility knife with an 18 mm blade and a sliding lock mechanism that provides adjustable blade extension and secure positioning. The set includes four replacement blades for continued use without interruption. The knife is intended for cutting cardboard, carpet, plastic and other common materials encountered in DIY, construction and packaging tasks, offering an ergonomic handle shape and a reliable blade holder for controlled, repeatable cuts.

Advantages

The sliding lock mechanism allows precise control of blade length and fixes the blade securely during use to reduce unwanted movement. The 18 mm blade width delivers a durable cutting edge suitable for heavier materials compared to smaller craft knives. Included replacement blades simplify maintenance and reduce downtime. The design supports quick blade changes without additional tools and the body provides a non-slip grip for improved handling and safety.

Suitable for

• Cutting cardboard and corrugated boxes
• Trimming carpet and floor coverings
• Cutting plastic sheeting and packaging materials
• General workshop and DIY tasks requiring repeatable straight cuts

Key specifications

• Blade type: Snap-off/replacement utility blades
• Locking mechanism: Sliding lock for adjustable blade extension
• Set contents: Main utility knife + 4 replacement blades
• Handle: Ergonomic profile with non-slip surface

How to use

Slide the locking mechanism to expose the required length of the 18 mm blade and ensure the lock clicks into place before cutting. Use steady, controlled strokes with the blade at a shallow angle to the cutting surface to maintain blade life and reduce the risk of slipping. When the tip becomes dull or damaged, unlock the holder, remove the spent blade segment or full blade according to the knife’s blade-change procedure and insert a replacement blade until it engages securely. After blade replacement, verify the sliding lock is fully engaged before resuming work.

Usage recommendations

For safe operation, always cut away from your body and wear appropriate hand protection when cutting dense or abrasive materials. Store spare blades in their original packaging and dispose of used blades in a puncture-resistant container. Regularly inspect the sliding lock and blade holder for wear and keep the mechanism free of debris to ensure reliable locking and smooth blade movement.
