How To Choose The Best Serrated Knife Sharpener

There is a myriad of knife sharpeners out there. Given that many knives now have serrations on their blade, it is pretty understandable that serrated knife sharpeners are also proliferating. 

Now, it is interesting to note that serrated knives have a different mechanism of sharpening. You require manual work on them. You just don't pass them into a carbide or ceramic stone for sharpening. Each of the teeth has to be refined so that you can retain its edge. 

Because of this, one cannot expect that standard knife sharpeners would work on serrated knives. A special section or mechanism should be dedicated to them. 

Each manufacturer has different means of sharpening serrated knives. For the most generic one, we have the ceramic sharpening rod. Most of the compact and pocket-sized sharpeners utilize this method. Considerably, this option is time-consuming but relatively inexpensive.

Moreover, it can create exceptional results if the knife has not been sharpened for a long time. They work if there are bents on the serration. Typically, ceramic rods are fine, having a grit of approximately 1000. 

Here is a video that indicates how you can use these rods to sharpen the serrations:

There are other conventional methods of sharpening serrated knives. And it is apparent how the sharpeners were constructed.

Take a look at the sharpeners by Work Sharp. They offer electric models but have different designs as to the conventional knife sharpeners for kitchen tools. You can immediately spot the difference in how their sharpeners are created. They appear like they have been engineered to suit the needs of every workshop.

Most of Work Sharp's heavy-duty sharpeners are using abrasive belts to sharpen serrated knives. You can treat this as an automatic sharpening as you just need to draw the teeth of the blade to the belt so that they can be refined. However, keep in mind that this method may not actually repair damaged or chipped blades. Again, if you are looking for something that can rejuvenate for serration, I do suggest that you get a ceramic sharpening rod. 

Sharpening And Honing: What's Their Difference

Because we have talked about refining and sharpening, there's a need that we can differentiate them. Despite having similar nuances, honing and sharpening are two different tasks. 

One can sharpen knives without honing them. Others can hone without the need for sharpening. Sometimes, you need both. 

All of these things are essential for serrated knives. Of course, the sharpener that you have must possess these functions to ensure their flexibility. 


Sharpening is the process of refining the blade of the knife that has no teeth already. If it is dull already, then it requires a major rejuvenation already. This is where sharpening takes place. 

When sharpening, you will need to chip out parts of the steel of the blade so that you can get a new edge. A damaged blade has to lose a lot of metal so that it can gain a new edge. 

Serrated knives have to be sharpened from time to time because most of their function requires cutting through hard objects. They are often used to deal with wood, rock, and other hard surfaces. Hence, they are more susceptible to damage than standard knives used for cutting food and other soft materials.


Meanwhile, honing is the process that ensures that a sharp blade will remain sharp. It will also remove some steel of the blade but at minimum levels only.

Honing is often recommended so that you don't sharpen your knife frequently. Of course, that would help you extend the life of the blade and its usability. Honing is considered as a maintenance procedure. It should be conducted religiously, especially if you are using your knives on rough applications.

Frequently Asked Questions About Serrated Knife Sharpeners
