What Is The Hole In A Knife Blade Used For?

By Ryan Leavitt •  Updated: 04/09/21 •  5 min read

Some knives are outfitted with several holes on the blade because these reduce the friction between the metal and the food being sliced, making it easier for the sliced ingredient to slide off the blade instead of sticking to it.

One problem many home cooks encounter when doing their chopping board chores is food sticking to their knives.

This is quite normal because of surface tension, especially with food that has high water content like fruits, vegetables, and root crops.

It’s almost impossible to get rid of those in your diet so adding features like holes on knives is a better solution to this common complaint.

There are other ways to minimize surface tension on blades:
The Japanese have been making knives with convex grinds on one side of the blade (knives or swords) for centuries. Hammering the steel so it has a crinkled texture or adding dimples on the edge also work.

But let’s focus on holes for now.


To reduce weight

It is no secret that the blade is the heaviest part and the reason for creating the hole can be the weight reduction.

Well, it may seem a bit nonsense, but if you compare the weight with and without a hole, you will feel the difference.

The cutting out of the small portion of the steel blade makes sense.

So we can say that one of the major reasons for creating it can be weight reduction.

Sounds weird?

Well, there can be some other reasons too.

To reduce friction

When I was researching the reason for the holes in knife blades, this seemed the most appropriate reason to me.

When you cut something using the knife, there is a considerable frictional force between the blade and the material being cut.

At the point where the hole comes, the force of friction automatically reduces and thus you can enjoy the smooth flow no matter how harsh or heavy the material is.

Though I have not practically experienced the reduction in friction, I agree with this reason.

For opening things

According to Spyderco—a high-quality knife company—the hole in the blade of a pocket knife that acts and replaces the thumb stud is becoming increasingly popular.

It may serve as the opening that allows the foldable knife to open conveniently.

Keep in mind that if your knife does not have a hole, it does have a thumb stud.

So if we compare both, the presence of these tiny slots seems more appropriate.

For hanging purpose

The most common and obvious reason is that it makes the knife hangable.

Here you might be wondering:

Does every knife need this feature for hanging purposes?

Well, keep in mind that hanging the knives is not only associated with butcher knives, but you can also hang knives of all types and shapes.

If you have a knife on the wall, you can easily get it and use it when needed.

It will save you from the hassle of finding the knife every time you need it.


Some people say this feature is for elegance and aesthetics.

They think that it gives the modern look to the knives and makes them more attractive.

It is due to this reason, the ancient knives did not have holes.

It can also be one of the reasons behind the holes.

So even if you imagine there is no use of a hole, this reason is always there to satisfy you.

In some countries, the slot in the pocket knife blade is regarded as a bold fashion statement.

Brand recognition

Not all knives have holes in the same place in the blades.

The position of the hole may reveal the particular brand.

Let’s understand it with an example,

Spyderco is a famous brand and uses the holes as the brand identity.

For this purpose, they have patented and noticeable holes in their knives and they have also implemented them in various styles and designing arrangements.

Spyderco is the company that used the holes for the first time for brand identification purposes.

That sounds like a unique idea as well.

If you are a knife brand and manufacture knives, or a buyer, you can always make the use of unique holes to understand and create the brand identity.


If you can think outside the box, you will find a lot of interesting benefits.

For example, if you insert the stick in the hole, you can use the knife for hunting purposes.

At this time, it will act as the true primitive hunting spear.

So yes, the presence of the hole in the blade makes it more stable and versatile.

Final Verdict

The presence of the hole is a unique addition to the knife’s blade.

Apparently, there are no considerable downsides to a hole, so you should not worry about it.

Do you have any other reason for having the hole?
