How Do You Use A Block Knife Sharpener? A Step-By-Step Guide

Sharpening may be the most practical way to maintain the knife’s quality. Thankfully, there are method tools for this task, such as a block sharpener.

How do you use a block knife sharpener? This tool comes with two honing steel sticks. All you have to do is pull your blade in and out between the steels to sharpen it.

We will discuss this tool in detail right here. You can also learn some extra tips for sharpening your knife. Let’s read on to discover!

What Is A Block Knife Sharpener?

The block sharpener is easy to use and quick to hone. It features a proprietary flex design that mimics the classic cutting edge of the knife.

This sharpener removes very little too often no steel from your knife while refining its razor-sharp in a short amount of time.

This tool is ideal for whetting different types of knives with different cutting edges. It can also work with serrated edge blades, hatchets, scissors, swords, and many other oddly shaped edges that other sharpeners can’t handle.

How Do You Use A Block Knife Sharpener?

This tool can work with different types of knives. Hence, we will divide the sharpening method into two sections: the tradition (bread, steak, and chef knives) and the serrated ones.

Traditional knives

Using this tool to work with traditional knives is easy. Let’s follow the steps below:

  • Start by putting the sharpener on the counter.
  • Use one of your hands to secure the grip on the edge of the countertop.
  • Squeeze your knife between the honing steels and repeatedly draw them in and out.

Serrated knives

These knives are more complicated to deal with due to their teeth. Here is how to sharpen them:

  • Place a towel on the countertop to minimize vibration during the sharpening process.
  • Use one of your hands to secure the sharpener on the towel. The sharpening angle should be about 60 to 70 degrees.
  • Draw the blade in and out so that its teeth can contact sharply with the honing steels.

Test the sharpness

After whetting, you can test if your blade is sharp enough by executing these experiments:

Tomato test

Herbs and tomatoes are two of the most delicate foods. They are also the canary when detecting whether a knife is sharp.

To check for sharpness, lay your knife’s edge on the tomato’s skin and pull it horizontally with gentle pressure.

You have successfully sharpened your knife if the blade goes into the tomato and cuts right through it.

However, if cutting the tomato demands more pressure, your knife is still dull and needs another sharpening round.

Fingernail test

The method is to touch the blade’s edge on your fingertip gently. It is sharp if the blade cuts into anything; if it slides or deflects, it’s still dull.

Begin tapping at the heel (nearest the handle) and work your way to the tip, checking for any sections that aren’t sharp.

Other methods work well in testing a blade’s sharpness. This video will show you some.

Why Is My Knife Not Sharpening?

There are tons of reasons why your knives are not sharpening. Usually, it is due to the blades themselves, the sharpeners, or the sharpening skills of the user.

Poor steel

Some cheap knives have steel that is too thin and too soft to give sharp edges. Such items will then get dull after using them a few times.

If you have a so-called blade, it’s best to throw it away and buy a new decent item. The cheaper it is, the more difficult it is to make it sharp.

Improper sharpening angle

The angles of each blade are different, depending on the respective sections of the application.

Kitchen knives usually have a 15 to 25-degree cutting edge angle, whereas outdoor ones have a 30-40 degree angle.

Knowing the optimal cutting edge is critical for sharpening the blade with the proper grinding angle. The angle of the grinding wheel is just half that of the cutting edge.

Unstable grinding angle

To make a sharp edge, the angle of your blade must be the same. Maintaining the grinding is not easy, and many beginners find it challenging.

You need some concentration and practice with carbon blades to keep it constant. They are straightforward to work with and become sharp quickly.

Honing steel is not hard.

The sharpening steel might be soft, whereas the blade could be as hard as, or perhaps harder than, the steel.

Because soft steel is less expensive, manufacturers prefer using this material to make the sharpening steel.

If the blade is harder than the honing steel, the steel will no longer be able to correct the cutting edge and accomplish its job. Hence, the honing steel should be harder than the blade it sharpens.

Blades of high quality and hardness, such as carbon knives, might be more difficult to sharpen than cheap steels.

The simplest solution is to get honing steel that is harder than your knives. The 10-inch steel is the best option.

How Do Self Sharpening Knife Sets Work?

Self-sharpening knives do not need any external tools to sharpen them since they come with an automatic sharpening mechanism.

You don’t need to hone any of your blades manually when you buy a self-sharpening knife set since they can sharpen themselves.

KIS technology

The KIS (Keep It Sharp) term refers to the built-in ceramic sharpener in every slot where you keep your knives.

The sheath has a set of hardened stainless-steel blades affixed to it. The blade sharpens by the edges when you remove or insert it into its slot.

During this procedure, the blade’s edge and the block’s edge rub against each other to sharpen the blade.

How to use the self-sharpening set?

Although each self-sharpening block has its own unique settings, most follow a similar mechanism.

Take the blade from the cutlery block and insert it within the slot for the sharpening mechanism to work.

It’s worth noting that sure sharpeners demand you to set the knife at a specified angle to sharpen it correctly.

In most cases, you’ll also have to draw the blade out of its slot and tilt it in a specific direction. Otherwise, it won’t even touch the ceramic sharpener when you pull the blade.


The block sharpener is among tons of sharpeners available in the market. You will find this tool easy to use. It can also work well at sharpening your blades.

Also, the self-sharpening block is a good idea to try. The auto honing mechanism benefits since you don’t have to hone the blade yourself often.
