When Should You Sharpen A Knife?

A serrated knife has amazing edge retention. This superior feature ensures aggressive cutting.  The pointed tip cuts with less tear and abrasion. In this way, you can cut your bread and tomatoes like a pro.

Without the need to be honed, a serrated knife lasts for years. The blade can retain its sharpness as it does not make much contact with your chopping board.

So, how will you know if it needs sharpening?

How to Sharpen Your Serrated Knife Using Ceramic Rod?

Sharpening rods are special tools that are designed to sharpen serrated knives. A ceramic rod is the best to use for honing a serrated knife. You have to make sure that your ceramic rod is highly polished for reliable results.

It should also have a maximum grit of 1500. For harder materials, you need a maximum grit of 1800.

A ceramic rod is perfect for sharpening all notches of a serrated knife from narrow, short to wide notches.

Follow the below technique to get a razor-sharp serrated knife:

Step 1

You require a working surface that is flat. You can place the serrated knife on this surface. You have to work on the side of the blade with serration. Make sure to keep this side facing upwards.

Now, you can place your ceramic rod into one of these serrations. You have to ensure that the ceramic rod perfectly fits into its V cut.  Additionally, it should align its bevel angle.

To avoid any mistakes, firmly hold the ceramic rod. Once you begin working on the blade, you will hear sharp sounds. It signals that you’re doing it the right way.

Step 2

You now have to slither the rod to the blade’s tip. Keep doing this until it gets shiny and smooth. Once you achieve this, you can move to work on the next serration.

You only need to do this a few times for each to get the results that you desire. Moreover, the ceramic rod is built with a much harder material. So, you do not have to apply much pressure while slithering.

Step 3

When you finish sharpening every serration, you can flip your knife for a finishing polish. You will notice that some steel residue is present on the blade’s flat side. Such residues are called burrs. You can feel them by running your finger along its flat side.

How can you get rid of these burrs? There are two methods to achieve this. You can do so by sharpening the flat side of your knife. You can do this on one whetstone.

Another method is to use sandpaper. Did you know that the silicone of the sandpaper is often considered to be the natural sharpener?  It can easily remove the burr from your serrated knife.

You now have a sharp and shiny serrated knife. You are all ready to get your smoother and cleaner cuts again!
