I’ve put together a buyer’s guide to get you up to date with everything there is to know in the world of proper knife maintenance. This guide will (hopefully) answer all the questions you might have about knife oil and review some of the most popular options available.
Also, I’ve included several of the best products in the market along with their pros and cons. That way, you can compare them and pick the right option for your collection.
Why Should You Oil Your Knives?
Modern knives are made from high-quality steel, but this won’t prevent them from eventually corroding with time. Needless to say, rusting is bad news when dealing with food and will reduce the effectiveness of your knife.
Long term exposure to rough and coarse materials or saltwater can permanently damage your knives. The best way to combat this and keep your knives in optimal condition is to regularly oil them.

How Do I Oil my Knives?
Step 1 – Cleaning
An old toothbrush and some soapy water work excellently for cleaning my knives. I then make sure to rinse off my knives in warm water to make sure no soap is left on them. Once this is done, I air-dry my knives for at least fifteen minutes before moving on to the lubricant.
Step 2 – Choosing Your Lubricant
At this stage, it’s time to consider exactly what type of lubricant to use. Knife oils come in a variety of viscosities from very runny to thick, treacle-like liquids.
You’ll want different oils for different applications, and it is important to consider what you want from your knife. If you are oiling the mechanism of a folding knife you may want a different oil than if you were oiling the blade of a kitchen knife.
You’ll also need to consider price points. Some knife oils don’t come cheap so if, like me, you like to keep your wallet strings tight, it’s best to shop around and see what’s the best bang for your buck.
For a more detailed look at some of the options available read my picks above.
Step 3 – Apply Your Lubricant
Once you have selected and purchased your knife oil of choice, it is time to move on to the final phase. It’s important not to go overboard when applying the lubricant.
Just a couple of drops will go a long way when oiling knives. The aim is to use just enough lubricant to evenly spread across the blade of your knife.
You can use a cloth or a cotton ear bud to apply the oil, whichever you find easier. As always when handling knives, take extra care not to injure yourself when applying the oil. Remember to wipe off any excess oil after the application is complete.
What Oil Should I Use on Wooden Knife Handles?
Wooden knife handles are susceptible to rotting and splintering if not properly cared for. Wooden handles come in two different types – stabilized and non-stabilized.
Stabilized wooden knife handles have pores, holes and extra space filled with resin, making the wood water-resistant and less likely to warp or lose form. Non-stabilized knives can swell and sometimes even crack with exposure to excessive water. The upside is that non-stabilized wooden knife handles usually retain a more natural look and feel than the stabilized version.
A mineral oil will protect both types of wooden handles and keep them looking and feeling new for longer.
How Often Should I Oil My Knives?
How often you oil your knives is completely up to you. Some people oil them after every use, some do it weekly, some only yearly and some never oil their knives. Personally, I recommend oiling your knives at least after every second use for best results.
Oiling your knife may cost more in the short term but it will increase the longevity of your knives and keep them in top condition. Trust me, oiling your knives regularly is well worth the effort.
What is Food Grade Knife Oil?
This is the type of oil that is safe to use on kitchen knives as it is able to interact with food without causing any issues. Food grade knife oil is non-toxic, odorless, colorless and flavorless. When searching for knife oil for kitchenware, it is essential that you make sure it is food grade knife oil.
The Bottom Line
It’s simple really. Keeping your knives well-oiled is paramount to their longevity and high performance. This is not something you can cut corners on, and investment in oils will pay off in the long term. As for which oils to use that is dependent on your personal preferences, requirements and, of course, budget.
The higher price brackets don’t necessarily equate to a better product and they might not be the sort of oils you need. Shop around and decide what it is that will suit your needs and how much you’re willing to spend to get that.
The bottom line is that whatever oil you choose to go with, you will be doing your knives a world of good. Keep them in better condition by oiling them with a suitable product once in a while at the very least.
