Here are some things to consider when choosing which is the best knife oil to use, and ultimately make sure you get the most life out of your blades.
Purpose of the Knife Oil
Which oil for knives you should use depends on which type of knife you intend to use your oil for and the purpose of this knife. There are two main reasons you would use knife oils, and these are:
- Kitchen knife care- Knife oil that you use for kitchen knife care is different to oil that you would use for maintaining knives that you use as tools. It is important that you choose a food-grade oil for kitchen knife care as some other oils are unsafe. Oils that are used for kitchen knife care, such as food-safe mineral oils, are usually applied to the blade.
- Folding and pocket knife care- Oils for folding knives and pocket knives are applied to the moving parts of the knife, so they are generally used for the purpose of lubrication or cleaning. If the blade is made from materials that will rust, then you can also use it as oil for knife blades.
It is essential to consider the materials from which a blade is made when making your decision about which oil for knife blades to buy. Consider the following:
- Some oils are not compatible with all materials, so it is important to check whether the oil is compatible with the materials from which you knife is made to avoid causing damage.

The Purpose of the Oil
Different oils have different purposes, so you should think about the benefits of each oil in relation to the reasons you are buying oil and choose accordingly. Just some of the benefits of oils available include:
- Rust prevention- Some oils will reduce the likelihood of your knife developing rust if you rub it into the blade. If an oil says that it will increase rust-resistance, it is a good choice for carbon steel knives.
- Lubrication- There are many oils that give a layer of lubrication, although this does not apply to all oils. When added to the moving parts of a knife, it stops them from grinding together and causing damage. It also keeps them moving smoothly.
- Protection- Many oils can protect your blades from damp or salt when applied to the blade.
