In the world of knives, every experienced user knows that a dull knife equals a dangerous knife. But, there is also another thing that makes the knife dangerous, i.e. lack of cleanliness.

For example, the knife’s function may be impeded because of pocket lint, which mostly collects in the pivot and locking parts. This makes the work slower and to becomes more difficult to open and close.

Unfortunately, folding knives could result in an injury or premature wear. This being said, it is essential to take good care of our knives and maintain them on a regular basis, not just with water and soap, but with lubrication as well.

You should use the best oil for folding knives once per month or so to help the moving parts work flawlessly.

Properly Oiled Folding Knife

However, nowadays, we have a lot of different lubricants for folding knives to choose from, so we can easily get confused.

This is where our review on knife lubricants can help! We will show you the best 10 options on the market currently, but also some of the most important things you should know about knife lubricants.

Why Do I Need to Lubricate my Folding Knives?

Without any doubt, if we want to keep our folding knives in ideal working shape, as well as our fixed knives, it is crucial to clean them on a regular basis and to lube them with the proper oil.

You just need a drop or two of the lube in the knife’s pivot to fight off grit and other friction-causing substances. What is great about these lubricants is that you can also apply them to the blade and thus, help avert rust and corrosion.

It is crucial to note that even in small amounts, the chemicals present in lubricants can come into contact with the food you are preparing and thus, enter your body. When ingested, they may cause numerous health issues.

With this in mind, it may be the best approach to use safe oils like mineral oil if you frequently use a specific knife for food preparation.

There are also manufacturers that produce lubricating oils from bio-based and food-safe ingredients.

From time to time, you should wipe the blades, joints, and springs of the knife with a cloth moistened with oil to lower the risk of corrosion and rust, especially if you live in a damper climate or close to water.

When your knife comes into contact with salt water or other substances that you are not sure about, rinse it right away and apply a thin oil coat and you are good to go!

What Kinds of Knife Lubricants Are there?

The most frequently used oils for folding knives are wet petroleum-based ones. These are the same as gun lubricants or oils for sewing machines.

Then, there are dry lubricants or Teflon-based ones and they usually attract less pocket lint. You can find them in an aerosol can for spraying application or in a grease tube. Either way, they dry on the surface and leave a lubricating and protective layer.

Last but not least, we also have food-safe lubricants which are best for knives that are regularly used for food preparation. Though you can use vegetable oil too, a much safer option is food-safe mineral oils.

You can find them in local pharmacies or specialized stores or order them online.

How Should I Use a Knife Lubricant?

Before you learn how to properly oil your folding and other types of knives, it is important to know that a little does a lot in this case. To lubricate your folding knife, first, you need to open it.

Apply one or two drops or lightly spray the pivot and begin to rotate the blade, i.e. open and close it repeatedly. This helps work in the oil. After you have applied the oil to the pivot and/or locking surfaces, make sure you remove any surplus lubricant.

This is important because too much of it may attract lint and other material and consequently, you will need to clean the knife more frequently.

If your knife’s blade is made from high-carbon stainless or true carbon steel, you can apply a preventive layer of oil, particularly if you use it around water or live in areas with high humidity.
