When using a grindstone, apply a little oil to the stone to lubricate and make the process easier.

And once you have just started using these tools, choosing the right oil can be quite confusing.

In fact, there are many people out there who ask if you can use olive oil to sharpen your knife.

The answer to that is yes, but it will not do a good job. You can use almost any oil to lubricate your grindstone, whether it is olive oil, mineral oil or even coconut oil.

That being said, some oils will do the job better than others, and when you sharpen a knife, the best oil you can use is honey oil.

So why are some oils better than others?

This is exactly what we will discuss in this article along with what properties to look for when looking for an abrasive oil.

Should I use olive oil for grinding?

Can You Use Olive Oil To Sharpen Your Knife

There are some chefs out there who use this material when sharpening their knives and it does not exactly do a bad job.

It does not harden, so you do not have to worry too much about clogging, but at the end of the day, this is a cooking oil and not one designed for grinding and polishing steel.

Since it is a food product, it will eventually develop a rather rancid odor that can become quite pungent if you leave it on.

So if you choose to use this to sharpen your knives, at least make sure to clean the stone completely and dry the knife down before storing it so that it does not develop an uncomfortable order.

There are many better choices out there when it comes to grinding lubricants, but if you have nothing else available, olive oil would work just fine.

What are the features of a good abrasive oil?

In this section, we look at what qualities you need to keep an eye on when choosing oil for your grindstone.

The purpose of using oil when grinding is to lubricate your stone so that almost all types can get the job done, but as we said before, there are certain qualities and properties that make certain oils a better choice than others.


This is one of the most important properties you need to look for in an abrasive.

This is also the reason why cooking oils like vegetable and olive oil are not the best choice for this purpose.

While they are able to perform the job quite well, they will develop a rancid odor if allowed to sit for a long time.

And if you have ever smelled rancid oil, you would know that this is not something you would want with your knives or stones.

The substance can get stuck in the stone, and if it becomes rancid, it will be difficult for yourself to get close to it, let alone use it for grinding.

So when looking for the right lubricant for your stones, be sure to choose something with a neutral scent and try to avoid cooking oils as much as possible.

The next thing to watch out for is whether the fabric hardens or not.

Grinding stones have pores, which is what sharpens your knives, and after a lot of use, some of the dirt can get stuck in the pores, making your stone useless.

Therefore, people make sure to clean their grindstone of any lubricant once they have used it to ensure that it does not get clogged.

That said, waste is not the only thing that can clog the pores.

There are certain substances that harden at room temperature, such as beef oil, which you would definitely know if you have ever cooked with beef.

Once the oil hardens, it can clog the pores of your grindstone and render it unusable. Therefore, make sure that the lubricants you use do not harden at room temperature, so that it will be easier to clean stones when you have finished sanding.

Low viscosity

Finally, make sure that the fabric you choose has a low viscosity.

Of the three qualities we have discussed, this is the only one that actually affects your grinding.

High viscosity and heavy oils can get in the way of a smooth stroke when grinding, which can get in the way of the whole process and result in you getting a wrongly sharpened knife.

On top of that, heavy fabrics can also end up staining your knives when sharpened.

To avoid this, always go for low viscosity fabrics to make the whole process more efficient.
