4.3 Safety Precautions

• Always handle the knife with care. The blade is extremely sharp.
• Keep fingers clear of the blade path when opening and closing.
• Do not use the knife for prying, hammering, or as a screwdriver.
• Store the knife in its sheath and out of reach of children.
• Ensure the blade is fully locked before applying pressure during use.

5. Care and Maintenance

Proper care will ensure the longevity and performance of your KATSU knife.

5.1 Cleaning

• Hand Wash Only: Clean the blade and handle with a soft cloth and mild soap. Avoid harsh detergents or abrasive materials.
• Drying: Thoroughly dry the knife immediately after washing to prevent rust, especially on the Damascus steel.
• Handle Care: The natural deer antler handle should not be submerged in water for extended periods. Wipe clean and dry.

5.2 Oiling and Storage

• Blade Oiling: Apply a thin layer of food-grade mineral oil or specialized knife oil to the Damascus steel blade periodically to protect it from moisture and maintain its finish.
• Pivot Point: A small drop of oil on the pivot point can ensure smooth opening and closing.
• Storage: Store the knife in its leather sheath or hessian sack in a dry environment to prevent corrosion.

5.3 Sharpening

The Damascus steel blade is designed to hold a sharp edge. When sharpening is required, use a quality sharpening stone or system appropriate for high-carbon steel. Maintain the original blade angle for best results. If unsure, seek professional sharpening services.

6. Troubleshooting

Here are solutions to common issues you might encounter:

• Stiff Opening/Closing: If the blade feels stiff, apply a small amount of knife oil to the pivot mechanism. Repeatedly open and close the knife to distribute the oil.
• Blade Dullness: If the blade becomes dull, it requires sharpening. Refer to section 5.3 for guidance.
• Rust Spots: Rust on Damascus steel can occur if not properly dried and oiled. Clean with a fine abrasive (like a rust eraser) and re-oil immediately. Ensure proper drying after each use.
• Handle Discoloration: Natural antler handles may change color slightly over time due to exposure. This is normal and part of the material's character. Avoid harsh chemicals.
