For this, we need a serrated knife sharpener, the so-called ceramic rod. Below there is a step-by-step guide on how to sharpen your serrated knives with a rod.

How to Sharpen a Serrated Kitchen Knife with a Rod?

How to Sharpen a Serrated Kitchen Knife with a Rod

The best tool to sharpen your serrated knife manually is a ceramic honing rod. A ceramic honing rod is harder than a steel honing bar, so the ceramic removes some of the material from the edge of the blade, which has a sharpening effect. The shape of the rod is designed to fit into the teeth of the blade.

Step 1:

With a slant, the edge finds the side of your knife. Generally, both sides of serrated knives look different. On the one hand, the blade surface continues to the blade edge at the same angle. While from the other side the blade is inclined slightly downwards just before the serrated edge; It is known as the bevel. Just use a sharpening tool on the slant edge.

Step 2:

Place the rod in one of the serrated scallops and as compared to the blade edge choose an angle between 13 and 17 degrees, blade edge is flatter than you are used to for sharpening knives.

Step 3:

When your rod is edged, place your rod where the diameter of the rod is slightly smaller or the exact size of the gullet.

Step 4:

Run the sharpening rod in many short passes on the primary groove. Push in one direction, far from the blade edge, toward your spine.

Step 5:

Check for “burrs” or metal chips by running your finger along the back of the groove. When you feel a burr so sufficiently you have sharpened the groove. This frequently requires only some strokes.

Step 6:

If the Serration of the knife is of various sizes then set the sharpening rod position so that the rod fills the groove.

Step 7:

Remove the burs by rubbing the back of the knife against a fine-grain sandpaper sheet. Alternatively, you can slide the sharpening rod lightly against the back of each groove; make sure to not apply pressure more than necessary to remove the shavings.
