How To Sharpen A Serrated Knife? Buyer’s Guide

Using a sharpening rod would be an essential step to sharpen a serrated knife. But this solution will be available only if you have the strength.

How To Sharpen A Serrated Knife

This solution and others will help you maintain your serrated blade sharpened. You can sharpen serrated knives unless you have one of those “throw-away knives,” which are cheap. In this case, it better to buy a new one.

 Admittedly, sharpening a serrated knife is not an easy task.  You cannot grind it easily as any other straight-edge knives. Fortunately, this type of blade doesn’t interact with cutting boards because of the serrations.

That is why you may not think about sharpening a serrated knife unless it has been a long time since you purchased it. So, I compiled 4 methods for sharpening your serrated blade in this article. These methods differ in their complexity according to the state of your knife and the tools you have.

Method 1: sharpen a serrated knife by a Ceramic Sharpening Rod

 Using a ceramic sharpening rod may be harder than the other methods. It also requires a lot of time. However, I have to note that the prices of the sharpening rods are inexpensive at all.

This method will Sharpen a serrated knife in the best way if there are any bent points on your blade, or it has been a long time since you sharpened it. Note that any serrated knife’s model will work with this method.

The Required Tools

  • Ceramic Sharpening Rod

Step 1: Choose the side of your serrated knife with a beveled edge

The serrations are only located on just one side of your knife. This serrated side has a part that is called a bevel. You will sharpen the other side just like any other straight edge. So, apply your rod only on the beveled side.

Step 2: Put the sharpening rod in each gullet

match the right angles with the serrated knife

 Grasp your serrated edge and let the tip of the knife away from you. Put the ceramic sharpening rod in each serration.

  Adjust the angle of the sharpening steel with each gullet so that it resembles the original sharpening angle.

Maintain that 13 and 17 degrees.

  • You can use a marker as a guide. If you remove the marker tag while passing the rod, then you are on the right track.

Step 3: match the sharpening steel with the diameter of the serration.

filling the serrations of the serrated knife

If you have a tapered-sharpening rod, fit the cone-rod with the serration. As a result, the diameter of the tapers is the same size as the serration.

  • Do not make the serration wide by choosing a different diameter. 

Step 4: wear gloves for your own safety

 Always wear gloves to avoid hurting your own body as the sharpener may tear your finger

Step 5: Sharpen the first serration

 Push the cone-rod through the serration with gentle moving, typically for a couple of strokes. You only have to push in one direction away from the edge of the blade until you reach the spine of the rod.

 I do not recommend passing the rod back and forth. Instead, you can rotate or flip the sharpening rod for a consistent sharpening.

  • Draw the cone-rod slowly away from the blade each time to protect yourself from the edge of the knife.

Step 6: Repeat the process for the desired progress

In this step, you just have to repeat the process of passing the rod through the serrations. It will take time.

 However, you will end with the best results. Eventually, it will take from 5-8 strokes to sharpen the edges of your knives if you choose the right angle. 

Step 7: use a leather strop to get all the burr removed

 After doing several strokes, you will get metal shavings, which are called “burr.” Pass the back of the knife against a leather strop, which will eliminate any burr. Then your serrated blade can provide you with the perfect slices.


Such a method that you will work on manually will sharpen a serrated knife perfectly. However, this chef’s kitchen tool needs effort. This sharpening steel works excellent for the 12-inches blades.

Even if you have a slanted edge, this method will work for you. The sharpening steel will not much store your kitchen’s utensils, but do not let your children approach it.
