Knife maintenance is useful to ensure the full functionality of the knife and its durability over time.

How should the maintenance be done?

Many knife manufacturers and makers who have high-quality knives ensure rapid replacement (unless the product is temporarily unavailable) in many cases such as:

  • manufacturing defect that undermines the functionality of the product;
  • caused by a defect in the realization or the defect inherent in the material.

Many provide the guarantee that covers knives indefinitely.

Ps. The linings or other parties have a lower guarantee from the date of purchase of the first buyer.

The warranty does not cover damage from wear and oxidation, which can be avoided, even on the best stainless steels, only with careful cleaning and lubrication.

To take advantage of this guarantee you clearly need to send the defective material with the original purchase receipt attached.

If defects not caused by the user are detected, the defective part is replaced for free and the company or maker takes charge of the return shipment.

But the important thing regardless of the warranty of the product is still the care and maintenance of the knife.

Here are some basic steps for maintaining a knife:

  1. Regular cleaning: After each use, clean the knife thoroughly with warm water and mild soap. Use a soft sponge or brush to remove food or dirt residue. Be sure to dry the knife completely after cleaning.
  2. Avoid the dishwasher: Avoid putting the knife in the dishwasher, as heat and moisture can damage the blade and handle over time.
  3. Regular sharpening: Keep the blade sharp with regular sharpening. You can use a manual sharpening machine or a sharpening stone. Follow the manufacturer’s instructions for best results. A well-sharpened knife is safer and cuts better.
  4. Lubrication: Apply a thin layer of knife oil or food-grade oil to the blade to protect it from oxidation. This is especially important if the knife is made of carbon steel, which is more susceptible to corrosion.
  5. Immersion in salt water: Avoid immersing the knife in salt water, as salt can cause damage to the blade and accelerate corrosion.
  6. Proper storage: Store the knife in a knife holder or sheath to protect the blade and to prevent accidental damage. Avoid leaving the knife exposed to moisture or direct sunlight.
  7. Fair use: Use the knife only for its intended purpose. Avoid bending it or dropping it on hard surfaces, as this may damage the blade.
  8. Periodic inspection: Check the knife regularly for signs of wear, damage or defects. If you run into problems, contact the manufacturer for repair or replacement if it is covered by the warranty.

Many manufacturers’ warranty covers manufacturing defects, but not damage due to wear or oxidation caused by lack of maintenance.

Therefore, even if you have a warranty, the care and maintenance of the knife is always crucial to ensure its longevity and optimal performance.

Knife maintenance

In case you want to make a repair, the maker usually offers the customer a service that repairs or replaces damaged parts.

The cost of the transaction will also be communicated to the customer upon receipt of the product to see if it is something technically feasible.

The re-sharpening service is for customers, free excluding shipping costs that are borne by the customer.

Most of a maker’s blades are made of the highest quality steel, with very high mechanical, cutting and oxidation resistance characteristics.

Despite this, the stainlessness of martensitical steels (from temper) does not have an absolute value but depends heavily on factors as diverse as the concentration of chromium, surface roughness, tempering modes, reagents with which they come into contact.

That’s why I suggest a few maintenance rules but that allow you to have an always efficient and functional knife that will best support you for a very long working life.

Here are some additional recommendations to keep your knife in top condition:

  1. Wear check: Regularly inspect the blade and handle of the knife for signs of wear, scratches or damage. Pay special attention to any loosening of the screws or pins in the handle.
  2. Re-sharpening: Although the re-sharpening service is free, you can learn how to sharpen the knife yourself. Learning how to use a sharpening stone or a manual sharpening machine can be useful to keep the blade always sharp between service and service.
  3. Fair use: Use the knife only to cut or slice food. Avoid using it for unintended purposes, such as opening boxes or cutting hard materials, as this can damage the blade.
  4. Thorough drying: After cleaning, dry the knife completely to avoid rust or oxidation stains.
  5. Safe storage: When not in use, store the knife in a safe place away from children. Use a knife holder or sheath to protect the blade and prevent accidental damage.
  6. Avoid acid: Avoid letting the knife come into contact with acidic foods or corrosive chemicals, as this may damage the blade.
  7. Periodic lubrication: Occasionally apply a thin layer of knife oil to the blade to protect it from oxidation. This is especially important if you live in an area with high humidity.
  8. Handle and sheath: Also keep the handle and sheath (if any) of the knife in good condition. Clean them regularly and inspect them for signs of damage.
  9. Follow the manufacturer’s instructions: Each knife may have specific maintenance needs depending on the material and design. Be sure to follow the manufacturer’s instructions to maximize the durability of your knife.

With these tips, you will be able to enjoy a reliable and efficient knife for many years. Regular maintenance is key to preserving the functionality and durability of your cutting tool.

Fixed blades

Knifemaker Drop Point KnifeAll plastic parts/wood/mipaper/bone/etc. Knife: handle, kydex rigid sheath or straps are made as materials with high mechanical and chemical resistance.

Accessory metal components such as screws, buttons and springs are made of metals that are virtually immune to oxidation.

The blade is the part you’ll need to pay the most attention to.

These rules must also be observed in case the blade is protected from surface treatments, these, in fact, as long as resistant, tend to wear out with use, leaving the surface of the blade bare.

The handle, easily disassembled, will facilitate these operations.

The blade is the part you’ll need to pay the most attention to.

These rules must also be observed in case the blade is protected from surface treatments, these, in fact, as long as resistant, tend to wear out with use, leaving the surface of the blade bare.

It is recommended to perform cleaning and lubrication operations using tampons and brushes, without dismantling the knife.

Too many disassembles and replacements can compromise the quality of assemblies and components.

In general

The knife should be kept dry and lubricated (specific synthetic lubricants or for weapons).

In case the knife is bathed with salt water it is necessary to rinse it with fresh water, dry it and lubricate it.

Salt water is the common worst enemy of hardening steels.

In case the knife is stored for a certain period of time, in case the knife is bathed with fresh water, in case it gets dirty with water-soluble materials such as mud: it is enough to wash it with fresh water, dry it and lubricate it.

In case the knife gets dirty with fatty materials it is necessary to clean it with common household detergents, dry it and lubricate it.

Make sure that the inside of the sheath is always clean, the dirt often contains abrasive matter that in uncovering and lining could scratch the surface of the knife.
