FAQs

What type of blades does this knife use?

This IRWIN knife uses standard 18mm segmented snap-off blades.

How many spare blades can be stored in the knife?

The knife features an internal cartridge designed to store two spare blades.

Is the blade retractable?

Yes, the blade can be extended and retracted manually, and secured with a manual screw lock.

How do I replace a dull blade segment?

Extend the blade, then carefully snap off the dull segment by holding the knife firmly and breaking the segment against a hard edge. Re-extend the blade to the next sharp segment.

What is the main advantage of the manual screw lock?

The manual screw lock provides a very secure and user-controlled way to fix the blade at a specific length, preventing accidental slippage or retraction.

Can I use other sizes of blades with this knife?

No, this knife is specifically designed for 18mm snap-off blades. Using other sizes may result in poor fit, damage to the knife, or safety hazards.

What material is the housing made of?

The housing is made of durable ABS synthetics with a steel blade guide.

Troubleshooting

Blade won't lock securely

Ensure the manual screw is turned fully clockwise. Check for debris in the blade channel or screw mechanism. If the issue persists, the blade channel or screw may be worn and require replacement of the knife.

Blade is difficult to extend or retract

Check for dirt or debris in the blade slider mechanism and clean it. Ensure the manual screw is sufficiently loosened before attempting to move the blade.

Blade snaps off unexpectedly during use

The blade may not be fully locked. Ensure the manual screw is tightened firmly. If the blade is dull, it requires more force which can lead to breakage. Snap off the dull segment and use a sharp section.

Internal blade cartridge is jammed

Gently open the end-cap and try to dislodge the jammed blades. Ensure blades are inserted correctly and not bent.

Pros and Cons

Pros

  • Secure blade locking mechanism with manual screw.
  • Built-in storage for spare blades enhances workflow.
  • Ergonomic textured grip for improved control and comfort.
  • Slim nose design aids in precise cutting and visibility.
  • Durable construction suitable for demanding tasks.

Cons

  • Segmented blade requires frequent snapping to maintain sharpness.
  • 18mm blade size may be too large for very fine detail work.
  • Plastic housing might be less durable than full-metal alternatives.
  • Manual screw lock adds a step compared to auto-retracting mechanisms.
  • Bi-metal blade, while durable, can be more brittle than high-carbon steel.

Setup, Compatibility & Care

Setup:

  1. Unlocking: Locate the manual screw on the side of the knife. Turn it counter-clockwise to loosen the blade mechanism.
  2. Blade Extension: Carefully extend the blade to the desired length.
  3. Locking: Turn the manual screw clockwise until the blade is securely locked in place. Ensure it does not move before cutting.
  4. Blade Replacement: Extend the blade fully. Loosen the screw. Snap off the dull segment by holding the knife firmly and carefully breaking off the used segment against a hard edge. Re-extend the blade to the next sharp segment and re-tighten the screw.
  5. Spare Blades: Open the hinged end-cap to access the internal cartridge and load spare blades.

Compatibility:

  • This knife is designed for standard 18mm snap-off blades. Use only compatible 18mm segmented blades.

Care:

  • Cleaning: Wipe the knife with a dry or slightly damp cloth. Avoid harsh solvents.
  • Storage: Store the knife with the blade fully retracted and locked in the 'safe' position. Keep away from moisture to prevent rust on the blade.
  • Blade Maintenance: Regularly snap off dull blade segments to maintain cutting efficiency.
