Every scallop point is serrated and these small points along the cutting edge give the serrated knife its role in your knife set because they allow it to tackle tasks that other kitchen knives aren’t suited to. These serrated edges are specifically designed for those foods that have a hard exterior and soft interior.

You should place the honing rod flat against the beveled edge angle to make sure you are doing it with the right angle, Then run it through the gilt toward the cutting edge and keep it with the bevel the whole time. Repeat the same process until you don’t sharpen all the gullets of the knife.

Remove the Burrs

While sharpening the knife, the small pieces of metal (burrs) will collect on the flat side of the knife.Remove these pieces of metal by running the flat end of the knife over a whetstone or a piece of fine-grit sandpaper. After all these things you will get a clean and sharp edge serrated knife.
