How to sharpen a serrated knife? A Step-By-Step Guide

Many people think that any knife has the same sharpening method. That is a misconception and causes your knives to break quickly. Sharpening serrated knives can be quite dangerous for inexperienced people. But thanks to this article, you will find it easier. Today, the Battersby will guide you on how to sharpen a serrated knife in the right way. 

How to sharpen a serrated knife?

  • Step 1: Prepare one sharpening rod and place them along the edge of each serration angle.
  • Step 2: Gently pull the sharpening rod through the serration
  • Step 3: Lift the grinding rod out of the serration 
  • Step 4: Do step 2 and step 3 about 4 to 5 times
  • Step 5: Burrs will appear after that process
  • Step 6: Move the sharpening bar again like sharpening a straight knife to remove all burrs

The first thing to notice is that sharpening a serrated knife is completely different from sharpening a straight blade. 

Therefore, conventional sharpening methods do not work with serrated knives. The special construction of the serrated knife makes it harder to sharpen than a normal knife. The trick here is to sharpen the serration one by one.

You need to prepare a sharpening rod and a blunt serrated knife. The sharpening rod is so familiar. You can buy it at any kitchenware supermarket. The sharpening rods are small and hard steel bars. 

You should choose a sharpening rod with a moderate length and a gradually tapered size. They will give you more options in size. This makes it easy to handle the small serrated parts of the knife.

  • How to hold the sharpener rod? Let’s hold the sharpening rod with your dominant hand, the serrated knife in the other. The side of the blade is facing your opposite side.
  • Place the serrated knife on the sharpening rod.
  • Place the sharpener rod according to the serration you want to sharpen (You can do this in turn until the end. Besides, you can also sharpen only the part you like as the middle part)
  • Slide the sharpener rod along the edge of the serration. Never sharpen the way you sharpen a straight knife. That may damage the knife immediately.
  • Do this about five times for each of the edges of each serration.
  • If you see a slight ripple of steel flake off, let’s stop. 
  • Follow this procedure until you see a thin strip of steel appearing on the blade. People often call them “burrs.”
  • Slide the sharpener again on the serrated knife to remove these burrs. This step is very easy. 

As a result, you’ve got a quality serrated knife as new.

Here’s what you should do if you want to keep your knife always sharp:

  • Do not put knives in the dishwasher. This makes the knife handle loose, causing collisions and friction. This also makes the knife dull and chipped.
  • Avoid wiping the knife with hard paper. Ideally, you should use a soft, highly absorbent cloth to wipe knives and scissors. Then you should hang them up to dry.
  • Blades made of carbon steel are prone to rust. Instead, you should choose stainless steel or a compound of carbon and stainless steel. An effective trick is that after cleaning and drying, you apply a very thin layer of cooking oil to the knife. The oil layer will prevent oxidation, preventing the knife from surface rust.
  • You should sharpen your knife with a sharpener or a serrated knife sharpener. Never grind into bowls and plates, as is the habit of many housewives. The use of a specialized knife sharpener will bring high efficiency and make the product more durable.
