How Does A Self-Sharpening Knife Work? Helpful Usage Guide In 4 Steps

Knives that self-sharpen are an excellent choice for any kitchen. You won’t have to go to the trouble of sharpening. So, how does a self-sharpening knife work?

Every time you pull it out to use it, the built-in sharpener will rub the knife. Ceramic sharpeners are located in each storage slot and sharpen your cutlery as needed. 

This method ensures that your cutlery is always ready to use, with the best cutting level and quality. When you slip the knife in or out of your knife, it sharpens automatically.

Understanding the way self-sharpening blades function can aid you in making the best purchasing selection possible. The most important thing is to select cutlery appropriate for your needs.

The following section describes how the built-in sharpener works and its benefits. Let’s have a look at it!

How Do You Use A Built-In Knife Block Sharpener?

Built-in knife sharpeners can be a convenient cutlery maintenance choice for anyone who uses kitchen knives frequently. But how can you put them to use? 

To utilize a built-in sharpener, follow these steps:

Step 1: Select the proper setting

Before putting the blade on the sharpener, make sure you set it to the correct setting. Some built-in sharpeners have a “Fine” or “Coarse” option.

The Coarse setting is for dull blades to be fully recharged, while the Fine location is routine maintenance.

Step2: Place the blade in the slot.

Next, remove the blade from the cutlery compartment. Please place it in the grinder starting at the base. Then, lower it and sharpen it with light pressure by bringing it towards you.

Repeat this method 2 to 6 times to sharpen the knife. Repeat this method 6–8 times if your blade is dull. You don’t want to damage the sharpening blade, so apply light pressure.

You will hear a grinding sound as you run the blade through the grinder. It is usually a sign that you are applying too much force. 

If the blade is jammed, remove it entirely from the grinder and discard it. Reinsert and try again, starting at the base.

You may encounter some resistance the first few times, but this is merely a sharpener’s way of removing dull edges from a knife. The more you sharpen your blade, the less likely this will happen.

Step3: Check the sharpness of the knife

Test the blade on a piece of food or paper after using the Fine Sharpness setting. Return to the “Fine” setting if the sharpness is not your liking.

Return to Coarse and run a few more times before going back to the Fine setting if you hear a solid grinding sound.

Step 4: Remove the knife and rinse it

Once you’re satisfied with the sharpness, clean it with warm soapy water and rinse off any steel debris around the handle or blade. You don’t want the residue to return to the block, so make sure you rinse the blade thoroughly.

Dry it with a clean cloth before returning it to its original position. Make sure to store the knives separately in drawers so that the edges do not scratch or lose their sharpness when they contact knives or other utensils.

By definition, they are knives that do not need to use an external sharpener. They usually come with a block that keeps the cutlery sharp for longer.

We already know that the self-sharpening knife set includes a block, a storage area for the knives, and a sharpener.

Knives that sharpen themselves automatically have a simple mechanism. When you use a self-honing knife, it points itself as you use it.

To make the sharpen function work, you must first remove the blades from their slots while tilting them down. Since the sharpener is at the bottom of the groove, if you pull the blade out of the groove at an upward angle, the blade will not contact the sharpener. 

Finish the gap with one or two pulls through the porcelain sharpener. Your blades will stay sharp when you need them if you employ this method.

What Is A Self-Sharpening Knife Block?

The block or sheath has a succession of hardened stainless-steel cutlery affixed to it. The cutlery sharpens by the edge when you remove or insert it into the block or sheath.

During this operation, the knife’s edge and the sheath or block’s edge glide against each other, decoying a tiny bit of steel from the block.

Sharpening the knives is the responsibility of the block. Keeping them in the league is necessary to buy a self-sharpening knife set. 

At least once a month, clean the block. Cleaning is a straightforward technique. Reverse the block and slowly and lightly bang on the floor or wall. It will remove the dust from the inside steel.

How Often Should You Sharpen A Knife In A Sharpener?

There is no precise figure for this. If your cutlery is already sufficiently sharp, you won’t need to use a sharpening.

If you believe your cutlery isn’t performing well, you should sharpen it. It has nothing to do with the number of times you put a blade through a sharpener.

It has everything to do with the cutlery you’re sharpening and determining the best method for pointing it.

Knife sharpening is a relatively low-cost service. You can have a knife sharpening set on hand for approximately $50 if you buy a DIY Knife Sharpening Set. 

A professional sharpening job will cost you $75 to $100 every two to three years, depending on the type and number of knives that require honing.

When seeing a professional, the price per knife is quite the same regardless of where you go. They will charge $1 to $2 per inch of the blade for each knife.

Depending on the shop and the specific blade type you have, it might vary somewhat, but this is what you will be paying as part of the flat cost.

For example:

  • Professional repair of broken knives or blade tips might cost anywhere from $5 to $20.
  • When having your cutlery sharpened, you may also have your blade thinned, which involves the sharpener reducing the breadth of the bevel beneath the knife’s primary edge, boosting its strength and performance. This service will cost about $10.
  • Sharpening a blade that is less than six inches long costs $7.00. This price covers removing typical tarnish from the blade.

You can quickly chop, slice, or dice any dish without having to waste time honing your knives. Yet, they will last less than if sharpened correctly with a wet stone. 

Anyway, if you use cutlery every week, you might want to consider utilizing a built-in knife sharpener to keep your blades in better shape.
