Why Does My Knife Get Dull So Fast?

By Ryan Leavitt •  Updated: 04/21/21 •  4 min read

A dull knife is not only hard to use but can also be a potential safety hazard.

The sharpness does not last forever as the cutting edge wears out due to continuous use.

Therefore, it is normal for your knife to become dull.

Even so, it should retain its sharpness for a long time.

So, why does your knife get dull so fast?

It is likely due to poor handling and lack of appropriate care and maintenance.

Cutting on hard surfaces, washing in a dishwasher, and wrong storage also makes a blade dull within no time.

Ideally, the blade should give you a few days or weeks of consistent performance before having to grind it again.

Therefore, if you notice that your blade becomes dull after every 1-2 days, then you should get concerned.

Learning how to maintain the sharpness requires practice.

Here are some of the reasons why.

Wrong grinding/sharpening

If you do not grind your blade according to the manufacturer’s instructions, then it goes without saying that the sharpness will not last for long.

When grinding, ensure that you use the right sharpener, sharpening technique, and angle.

Inappropriate use

If you use a chef knife for cutting through frozen food and hard surfaces such as bones, then you should expect your tool to become dull within no time.

Due to this, it is necessary that you only use a blade for the right cutting purpose.

Ensure that you invest in a large collection of blades so that you have the right blade for every task in the kitchen.

Also, it is crucial that you only cut on a chopping board as opposed to hard surfaces like ceramic countertops.

Washing in a dishwasher

When you wash your cutter in a dishwasher, then you can be certain that it will become dented and dull.

Usually, the collision between it and other utensils in the dishwasher damages it.

As such, it will become dull within no time.

It is advisable that you only hand wash your blades.

Use a piece of cloth and a mild detergent to wash it under running.

Then rinse it and dry it before storing it.

This helps in preventing rusting and corrosion.

Inappropriate storage

Storing your kitchen blade wrongly will also make it dull fast.

Invest in a quality storage block or magnetic strip.

Do not throw your knives in a drawer or leave them lying carelessly on the countertop.

This is not only potentially dangerous but also can cause damage to the edge especially if it falls.

When storing your blade, always ensure that you keep it away from moisture or heat.

Using it for irrelevant tasks

More than once, you may find yourself tempted to use your knife for other tasks other than the intended cutting, slicing, dicing, or chopping tasks.

Do not use your blade for unscrewing electronics, opening cans, and cutting boxes open.

These tasks cause dullness to the edge and can even make the cutter break.

Always ensure that you use your blade for its intended cutting tasks.

How can you keep the sharpness over time?

Once you sharpen your blade, there are several ways through which you can maintain the sharpness.

Some of these ways are:

Hone regularly

A honing rod comes in handy for restoring the sharpness and straightness without having to sharpen every now and then.

Hone your cutter a few minutes before you start cutting through any food.

Proper technique

Use the right technique when cutting with your blade.

Hold it accordingly and always cut in a rocking motion.

When it comes to sharpening, maintain the right angle for accurate sharpening.

In essence, you should follow the manufacturer’s provisions when it comes to sharpening and using the blade.

Take good care

For starters, you should never soak the thing in water.

This not only damages the cutting edge and handle but can also inflict severe injuries.

With the right care and maintenance, you can expect your knife to last for long while still giving you the best performance.

A Bonus Tip

You should never leave yours to air dry.

Instead, always dry it with a tissue or a clean dry cloth.

This goes a long way in preventing rust and corrosion.


A dull knife requires more effort and pressure to slide through food.

This, in turn, means that there is a higher chance slipping from the hands and causing severe injuries.

As such, you should always keep your blade sharp.
