4. Setup and Blade Extension

To prepare your KINZO Hobby Knife for use:

1. Carefully remove the knife from its packaging.
2. Locate the blade slider mechanism on the top of the knife handle.
3. Gently push the slider forward to extend the blade to the desired length. The slider will click into place at various increments, securing the blade.
4. Ensure the blade is firmly locked before beginning any cutting task.
5. To retract the blade, push the slider backward until the blade is fully enclosed within the handle.

5. Operating Instructions

These knives are designed for precision cutting of materials such as paper, cardboard, thin plastics, fabric, and other craft materials.

• Grip: Hold the knife firmly but comfortably, ensuring a secure grip on the handle.
• Cutting Surface: Always use a self-healing cutting mat or a protective surface underneath your material.
• Cutting Technique:
  • For straight cuts, use a ruler or straight edge as a guide.
  • Apply steady, even pressure. Multiple light passes are often safer and more effective than one heavy pass, especially on thicker materials.
  • Angle the blade slightly for a cleaner cut, but avoid excessive angles that could cause the blade to snap.
• Blade Sharpness: A sharp blade is safer and more efficient. Replace blades as soon as they become dull or damaged.

6. Blade Replacement

Replacing a dull or damaged blade is essential for safety and optimal performance. Refer to the safety instructions before proceeding.

1. Retract Blade: Ensure the blade is fully retracted into the handle.
2. Remove End Cap: On the larger knife, there is often a removable end cap that also functions as a blade snapper. On both knives, the blade can be removed by fully extending it and then carefully pulling it out from the front. Some models may have a button or lever to release the blade. (Note: Specific mechanism not detailed in product description, general instruction provided.)
3. Dispose of Old Blade: Safely dispose of the old blade in a sharps container. Do not discard in regular trash.
4. Insert New Blade: Carefully slide a new blade into the blade channel from the front of the knife, ensuring the cutting edge faces the correct direction.
5. Secure Blade: Push the blade until it clicks into place or until the end cap is reattached, ensuring it is securely held by the slider mechanism.
6. Test: Gently extend and retract the new blade to confirm it operates smoothly and locks securely.

7. Maintenance and Storage

• Cleaning: Wipe the knife handles with a dry or slightly damp cloth to remove dust or debris. Do not immerse in water.
• Lubrication: If the blade slider becomes stiff, a small amount of dry lubricant (e.g., graphite powder) can be applied to the mechanism.
• Storage: Always store the knives with blades fully retracted in a dry, safe place, away from moisture and out of reach of children.

8. Troubleshooting

• Blade not extending/retracting smoothly:
  • Check for debris in the blade channel. Clean if necessary.
  • Ensure the blade is correctly seated.
  • Apply a small amount of dry lubricant to the slider mechanism.
• Blade feels dull or tears material:
  • The blade needs to be replaced. Refer to Section 6: Blade Replacement.
• Blade wobbles during use:
  • Ensure the blade is fully extended and locked into one of the slider's increments.
  • Verify the blade is correctly inserted and secured within the knife body.
