A serrated knife is usually used for cutting bread and other kinds of crunchy food. It is very efficient and durable. However, as any knife, it can become dull. When it happens, the blade starts to tear the food instead of cutting it. Due to its distinctive edge shape, a serrated knife cannot be sharpened as a regular blade. Today we will share with you two methods for putting a sharp edge on any serrated knife. With the right technic and tools, you can do the job quickly and with the slightest effort.

Obviously, the easiest way to sharpen any knife is to use a professional electric sharpener. It does sharp serrated knives as well. And the process will take you even less than a minute.

Unfortunately, not all of us can afford such appliances. Luckily, there is a way to sharpen serrated blade manually with the help of inexpensive tools.  But before we talk about the sharpening process, we need to clarify some rules.

Rule #1 You should never try to sharpen a flat side of a serrated knife. The serrated blade needs to be sharpened only at one side. This side is called bevelled and has serration, usually of different sizes.

Rule #2 You need to sharpen only clean knives. Make sure to remove all the dirt before starting the sharpening process. If you find any rust spots at your blade, you may want to get rid of such knife because it is of poor quality and hence useless.

Rule #3 Always wash your knife after sharpening. Never use a blade, especially for cutting food, if you don’t wash it thoroughly after sharpening its edge. You may not notice, but there are always some tiny metal particles left after sharpening. Trust me, you don’t want to spice your meal with them.

Tools for Sharpening Serrated Knives.

Our customers usually buy the diamond or ceramic rods, because they are the most efficient and easy-to-use. The rod with tiny tip will help you sharp even the smallest gullets. Remember that you can never use a flat sharpening stone  for edging serrated knives because you risk destroying your blade.

Sharpening Process

Start by placing your knife at some firm surface and grasp it tightly to secure its position. Take a sharpening rod and place its tip to the first gullet of the blade. Try to adjust the angle of the rod to the angle of the knife’s edge. Then slightly move the rod downwards. Don’t make any firm moves. Let the sharpener do its job. Remember that you need to move the rod only downwards, because if you pull it upwards, you can damage a gullet. You should avoid using a sharpening tool with the too fat rod because it can lead to teeth damage as well. Make a few downwards passes at one gullet and move to another. Repeat the process until you sharp all of the gullets on the blade.

There are some blades with serrations of different sizes. To sharpen such blades you need to either have several rods of different diameter or a one triangular rod. The triangular rod can be adjusted to any gullet. You can sharpen even the smallest serrates with its tip and use its middle part to improve the cut of larger gullets.

Don’t forget to remove the burr after sharpening. To do that turn the blade to the opposite side and slightly polish its edge. Do it carefully without any pressure. To make your knife completely ready for using, wash it with some liquid soap and dry it out.
