How to sharpen a serrated knife with a rod?

It is not a difficult job just follow these steps if you already know about it then you will revise it. ..

The Easy Method


1st hold your ceramic rod in your hand, Carefully check the tip of the rod touching the kitchen countertop.


On the flat side of the serration, lay your knife perfectly flat.

*Be careful*

It is a careless way If you run the knife on the rod in this same position, it will scratch up the surface.


So to avoid that to happen, we raise the knife just a hair and start running the blade backward. There will be a sound like a telephone ring to hear because it is serrated. But for it you should do right and hit the right angle, that is the sound you will hear.


This is the key, Please do not put much pressure on the knife, because ceramic has a very minute amount of metal and harder than steel, it is so trivial that you won’t notice The part of ceramic which is trying to sharpen your knife will be going gray, by observing that you will decide how much strokes should apply, It depends on your knife condition. The same methods apply to smaller serrated knives with smaller narrow serrations, and the sound will be like a stack of cards.


After doing this, it is creating a bit of a burr and a bit of a wire edge, and it is rolling the knife mettle over. You should repeat it for 30 or 40 times but depend upon the condition of the knife, you will notice that a thin wire edge is developing inside the scallops, but that’s perfectly fine.


Check the  other side, the side which was actually being rubbed on the rod,

  • There will be much of the metal taken off after this process,

And you won’t see any scratch marks along the flat side, because as I have described that the ceramic is harder than the steel, so it is also polishing the knife steel.

Please keep in mind:

The knife strokes backward when you are moving the metal down towards the primary cutting edge, and it will form a burr, which you can feel if you run down your fingers flat over the scallops. Because the steel side of the knife has moved towards the main cutting edge. So now we need to move the burr back for the serrations to be straight.


For that purpose, we need corrugated cardboard


corrugated cardboard

Why cardboard?

Cardboard has a silicate’s surface, and silicate is a natural sharpener. The corrugated surface of the cardboard grips the serrated scallops of the knife, and we use it to remove the burr or the wire edge and will bring the knife forward.

Last Step-8

Place the cardboard on the flat surface and make a little hump on the cardboard. Because the crease on the cardboard goes inside each scallop and removes the burr. Lay your knife perfectly straight on the cardboard, If you do it right, you will notice that the cardboard will latterly lift itself into the scallops.


So just like on the ceramic rod, lift the knife a bit, and gently stroke backward. It’s minimal polish.

So what is this is going to do is that it is going to polish off the burr? Do this for 1.5-3.5 mins on both sides, it also depends on the condition of the knife.
