Utility Knife Irwin IW4042202 — retractable blade, durable design

Irwin IW4042202 is a utility knife with a retractable blade and a durable design intended for general cutting tasks. The tool combines a compact body with a mechanism for safely extending and retracting the blade, enabling controlled cutting and secure storage. Its construction is aimed at frequent use in workshops, construction sites, packaging operations and DIY projects where a reliable, easy-to-handle cutter is required.

Advantages

The retractable blade mechanism provides quick and secure blade retraction to reduce the risk of accidental cuts during handling and storage. The knife's durable housing and solid internal components are designed to withstand repeated use and moderate impact associated with daily jobsite tasks. Ergonomic shaping supports comfortable grip and control for accurate cutting, while the straightforward blade change process helps minimise downtime when a fresh edge is needed.

Suitable for

• Cutting cardboard, tape and packing materials
• Trimming drywall paper and insulation
• General workshop cutting and material preparation
• DIY home improvement tasks and hobby projects

Key specifications

• Blade type: retractable utility blade compatible with standard snap-off or utility blades
• Handle: durable, impact-resistant body with ergonomic grip
• Blade action: manual slide mechanism for extension and retraction
• Intended use: general-purpose cutting for workshop, construction, packaging and domestic tasks
• Safety: blade fully retracts into the handle for safer storage

How to use

Slide the blade control to extend the blade to the desired cutting length and ensure the blade is locked in position before use. Hold the knife with a firm grip and make controlled, steady cuts, applying consistent pressure appropriate to the material. After cutting, retract the blade fully into the body for safe handling and storage. When the blade becomes dull, follow the manufacturer's instructions to replace it with a compatible utility blade, ensuring the knife is in the closed position during the replacement process.

Usage recommendations

Always wear appropriate personal protective equipment such as cut-resistant gloves and eye protection when cutting. Use the knife for its intended materials and avoid excessive force or prying motions. Store the knife with the blade retracted and away from children. Regularly inspect the housing and blade mechanism for wear and replace components if they compromise safe operation.
