Why Won’t My Knives Stay Sharp?

Owning knives comes with a responsibility to maintain your knives to ensure that they stay sharp and are ready for use at all times.

However, there are certain strategies you can use to keep your knives sharper for longer periods between sharpening sessions. Before we investigate what you can do in this regard, take a look at what causes your knives to lose sharpness.

Understanding the situations that affect a knife’s sharpness will give insight into keeping the knife’s edge at optimal sharpness.

Why Do Knives Lose Sharpness?

There are many reasons for a knife losing sharpness; some are preventable, while others are due to normal use of the knife.

Being aware of these causes for a knife losing sharpness can help you to be more cognizant of these issues when using or maintaining your knives.

Reasons knives lose sharpness include the following.

  • Quality of the steel. A knife made from poor-quality steel or soft steel will not hold a sharp edge for very long and will lose sharpness every time you use it.
  • Impact on a hard surface. Using the knife on a hard surface will dull the knife.
  • Inappropriate use of the knife. Using a knife to cut something it was not intended to cut will cause the blade to dull faster than expected or damage the cutting edge.
  • Incorrect storage of the knife. Storing the knife in a manner that does not protect the edge is a major cause of a knife losing sharpness.
  • Improper washing of the knife. The way a knife is washed can reduce the sharpness of the knife.
  • Incorrect sharpening of the knife. If the knife is not sharpened to the correct angle on the secondary bevel, it can affect the edge holding capability of the knife.

The cause of a knife losing sharpness is when the fine, thin metal on the cutting edge rolls over to one side or the other or when the edge becomes wavy or out of alignment with the knife’s spine.

Why Does My Knife Get Dull So Fast?

If you are having an issue with knives losing their sharpness fast, you may be interested in some of the main reasons this is happening.

The most common reason for knives losing sharpness fast is due to poor-quality steel used in the manufacture of the knife. The only way to avoid this issue is to purchase quality knives rather than cheap grocery store knife sets.

The second most common reason for knives becoming dull fast is when knives are used for purposes for which they are not intended. This problem is especially prevalent with kitchen knives, where it is easier to reach for the closest knife on hand rather than retrieve the right knife for the task.

The final most common cause for knives becoming dull fast is incorrect storage and cleaning of the knives. Give your knives the correct treatment when cleaning or storing them to overcome this issue. We have some tips regarding storage and cleaning that will help you avoid this problem with your knives.

For those knife owners that sharpen their own knives, there is also the possibility that you are not maintaining the correct angle when sharpening the knife. An inexperience with sharpening can result in incorrect sharpening angles.

A knife sharpened at an incorrect angle for the design of the blade will result in a knife that does not hold its edge very long and will become dull quickly when used. 

TIP: We all know that knives are meant to be sharp and that a dull knife is said to be more dangerous to use than a sharp one. But can be knife too dull to sharpen? Find out the answer in the article below:

How Do You Keep Your Knife Sharp Between Sharpenings (Longer)?

How Do You Keep Your Knife Sharp Between Sharpenings?
How Do You Keep Your Knife Sharp Between Sharpenings?

One of the key aspects to increase the longevity of your knife is to reduce the frequency with which you sharpen your knives. Knife sharpening removes metal from the knives’ cutting edge, which reduces the knives’ useable life.

It is not feasible or safe to work with a dull knife, so how can you keep your knives sharp between sharpenings to extend the time interval between sharpenings?

We have some tips on keeping your knife sharper for longer, which will help you reduce the frequency of sharpening without running the risk of working with a dull knife.

TIP 1 – Hone Your Knife

A knife can lose some of its sharpness, making the edge not keen enough to work efficiently but not dull enough to require sharpening. Honing a knife’s edge is a way to keep the knife sharp without taking it to a coarse whetstone and removing too much material unnecessarily from the edge.

The edge experiences wear with the normal use of a knife and can roll over slightly or become misaligned from the blade’s axis. This can cause the knife to feel like it has lost some of its sharpness and that it requires sharpening.

In most cases, the knife does not require sharpening but rather honing, which re-aligns the cutting edge ad restores sharpness to the blade. Honing does not remove metal from the edge of the knife, making it less destructive on the blade than sharpening.

Frequent honing will keep the knife sharp for longer and increase the time between major sharpening sessions required on the blade.

The way to hone your knife will depend on the type of knife you have and the tools you have available for honing.

The tools you can use to hone a knife are as follows.

  • A honing rod. A honing rod, sometimes called honing steel, can be used to re-align a knife’s edge. Honing rods can be made from ceramic, diamond, or steel material. The only knives you should never hone with a honing rod are Japanese kitchen knives .
  • A high grit whetstone. A whetstone with a grit level of over 1000-grit can be used as a honing stone. The sharp edge can be restored with 2 or 3 passes of the blade over the stone. One of the best grits to use for honing is a 3000-grit whetstone. This honing method can be used on all knives, including Japanese kitchen knives.
  • A leather strop. A leather strop is simple to use, and you can make your own strop with a few basic DIY skills. The leather strop must have a firm backing, such as a woodblock. All knives can be honed on a strop, including Japanese kitchen knives.

Honing your knife can be done once a week or as often as the edge needs to be touched up to restore sharpness.

TIP 2 – Store Your Knives Correctly

Correctly storing your knives is a key discipline that will help to keep your knives sharp. Many people make the mistake of keeping their knives in a kitchen drawer with other kitchen utensils with the blade unprotected.

The knives will get jostled about in the drawer, causing the cutting edge to become dull from impact with other knives and utensils and even the draw itself.

Your knives should be kept on a good quality magnetic wall-mounted strip, a quality knife block, or with individual blade covers.

The only way to store knives safely in a kitchen drawer with other utensils is to have individual blade covers or sheaths for your knives. Many Japanese kitchen knives come with their own custom wooden sheath for this purpose.

TIP 3 – Clean Your Knives Correctly

Many people are not aware that incorrectly cleaning a knife can cause the knife to become dull and even damage the thin cutting edge.

The worst method to clean your knives is to pop them in the dishwasher. The high pressure of the water in this machine will cause the knife to bounce around in the rack and possibly collide with other items in the machine.

This excessive impact during the machine’s cycle can negatively affect the knife’s cutting edge, resulting in the knife losing sharpness or sustaining severe damage to the cutting edge.

The best method to clean your knife is under warm running water and using a soft cloth with some mild dishwashing soap. Once the knife has been washed and rinsed, thoroughly dry the knife before storing it.

TIP 4 – Don’t Cut On A Hard Surface

Hard cutting surfaces are not friendly to the sharp edge of a knife. Cutting on a hard surface can roll the knife’s sharp edge, push the edge out of alignment, chip or even crack the fine metal edge of the knife.

Surfaces that should not be used to cut on are ceramic plates, granite countertops, glass cutting boards, granite cutting boards, or metal prep tables.

These surfaces can quickly dull the knife’s cutting edge, requiring a sharpening session to restore the edge. 

To avoid an increased frequency in sharpening your knives, you should avoid using these hard-cutting surfaces for your food preparation.

Wood, bamboo, and food-safe plastic cutting boards are better for the health of your knife’s cutting edge and reduce the amount of sharpening your knives will require.

TIP 5 – Don’t Drag Your Knife Across The Cutting Board

Many people are in the habit of sliding the sliced ingredient out of the way by pushing the chopped or sliced sections with a lateral dragging movement of the knife across the cutting board.

While this may be an efficient movement to clear your work area, particularly if you have some more slicing or chopping to do, it can be detrimental to your knife’s cutting edge.

Most cutting boards have ridges and grooves and various imperfections on their surface from use over time. Dragging the sharp edge sideways across the imperfections on the cutting board can roll the edge or push it out of alignment.

This technique is particularly unhealthy for high carbon steel Japanese kitchen knives since it can cause gouges and chips in the sharp edge.

If you use this technique, you need to lift the knife slightly to ensure it does not contact the cutting board when you push the ingredients out of the way.

How Do Professional Chefs Keep Their Knives Sharp?

Professional chefs know the value of keeping their knives sharp and on the cutting edge in optimal conditions. Many professional chefs use expensive knives, which is additional motivation to keep their knives in good condition.

Most professional chefs will keep their knives sharp by regularly honing the edge. Honing is usually done immediately before using the knife in the kitchen and after using the knife. After use, the knife is usually washed, dried, and honed before storage. The knives will be sharpened every 4 to 6 weeks.

Many professional chefs do not sharpen their own knives but prefer to outsource this task to experienced knife sharpening professional services. This way, they can be sure their knives are sharpened to the correct angle, and the edge will be durable.
