DeWALT DWHT0-74432 retractable utility knife

DeWalt DWHT0-74432 is a retractable-blade utility knife with a single-blade design and a metal body built for repeated use in workshop, construction and domestic environments. The tool provides straightforward cutting of cardboard, plastic, carpet and general trimming tasks while offering a compact form factor and controlled blade retraction for safer handling. Blade replacement is designed to be simple and quick to minimise downtime.

Advantages

The metal body gives improved durability and impact resistance compared with typical plastic-handled knives, while the retractable mechanism allows the blade to be fully withdrawn when not in use for safer storage. Its single-blade layout reduces moving parts and simplifies blade changes. The compact size and balanced weight support steady control during precision cuts and heavier slicing tasks alike. Materials and construction focus on reliability under repeated on-site use.

Suitable for

• Cutting corrugated cardboard and packaging
• Trimming plastic sheeting and film
• Installing or cutting carpet and flooring underlay
• General workshop trimming, opening boxes and light demolition tasks

Key specifications

• Design: retractable single-blade utility knife
• Body material: metal housing for increased durability
• Blade system: quick-change single blade compatible with standard utility blades
• Operation: manual slide for blade extension and retraction
• Ergonomics: compact profile with textured grip areas for controlled handling

How to use

Slide the blade forward using the manual slider until the blade reaches the required cutting length and lock it if applicable. Position the blade at the intended start point, apply steady, controlled pressure and cut along the material using smooth strokes; use multiple light passes for thicker materials rather than forcing a single deep cut. Retract the blade fully when the tool is not in use and store it with the blade withdrawn. Replace the blade following the manufacturer's blade-change procedure, ensuring the replacement blade is seated correctly before use.

Recommendations

Always wear appropriate hand protection and eye protection when cutting. Keep the blade retracted during transport and storage. Replace blades when dull to maintain cutting performance and reduce the force required, which lowers the risk of slips and accidental damage.
