The way to sharpen a serrated knife is to leave the flat side of the blade edge alone until the very end. Your main focus will be on each individual curved serration to result in the perfect blade.
You will need a tapered sharpening rod to sharpen a serrated knife.
How to Use a Sharpening Rod
A sharpening rod is narrow and tapers to a point. It actually has various thicknesses along the entire shaft. You will want to pay close attention to those thicknesses. It is best to choose the thickness that matches the width of the serrations on your knife.
Once you find the thickness that matches the serration, all you need to do is drag the rod across the serration. It is important to keep the rod flush with the serration. If you don’t, you won’t have the correct angle and the knife won’t sharpen properly.
There are no specific guidelines as to which way you should drag the sharpening rod. However, we recommend dragging it away from the blade. This will ensure you won’t slip and cut yourself.
To get your serrated knife have sharp blades, it is best to drag the sharpening rod four or five times over each individual serration. Also, go in one direction and never drag it in a back-and-forth motion. Yes, it will take a while since most serrated knives have at least 30 serrations. However, it is not a difficult task, do knife maintenance and the result will be a sharp knife.
Remember that there are several types of sharpening rods. Some of them are listed below:

As soon as you are finished sharpening all the serrations, it will be time to flip the knife over. Sharpening the serrations will have created a burr. That burr will need to be smoothed out before you can use the knife again.
To remove the burr, simply stroke the flat side on a regular sharpening stone a few times. If you do not have a sharpening stone, you can use a piece of fine-grit sandpaper.
It is important to wash and dry the knife before using it, to remove any dust or debris that was created by the sharpening process.
You can use an electric sharpener to sharpen your serrated knives. Simply turn the electric sharpener on and swipe the blade. You will want to swipe the blade towards you. Most of these electric sharpeners focus on the flat side and not the scalloped side of the knives. Therefore, if the serrated portion of your knife is dull, these sharpeners will not be as effective.
