Can you sharpen a serrated knife with steel?

Did you know?

Toothed knives, despite being able to hold the edges for a long time compared to straight edges, also require sharpening to restore their sharpness. However, these knives are difficult to sharpen and therefore require you to use the right grinder.

Serrated blades are ground differently and use different sharpeners than those used for straight blades. While sharpening these knives is complex, you can do it yourself as it is a self-explanatory task.

With serrated knives, carefully pass the sharpness through each sawtooth. This helps ensure that all the teeth in the blade are ground evenly.

How to use

Can You Sharpen A Serrated Knife With A Steel

Steel rods are quite easy to use when sharpening saw blades. Most saw grinders for saw blades have a taper to accommodate different tooth sizes. The steps you need to follow include:

Find the sloping edge of the blade

Serrated leaves are not identical on both sides; one side is inclined while the other is not inclined. On one side of the blade, the blade continues at the same angle from the handle to the edge of the blade. On the other hand, however, the face of the blade angles slightly downward in front of the serrated edge. This is the sloping edge of the blade. Only drive the bar on the sloping edge.

Place the rod in one of the teeth

It is quite easy to identify the right angle of the sawtooth. This is because you can count on the slope to guide you. The perfect angle for these knives is 13-17 degrees. Once you have identified the correct angle, the next thing you need to do is place the bar in one of the esophagus.

If your rod has a taper, find the point where the diameter rod is equal to the size of the teeth or slightly smaller.

Grinding of the first sawtooth

Run the steel along the first saw cut in short uniform strokes. Push the rod in one direction toward the spine and away from the edge of the blade. For even grinding, turn the rod slightly.

Make sure you only push the rod to the point where the teeth are the same diameter as the rod. This prevents the sawmill from enlarging.

Check for burrs

When you have finished grinding your serrated blade, run your fingers behind the glove to check for metal chips or a burr.

Once you have noticed a burr, it is clear that you have sharpened the groove sufficiently. You can run a few strokes of the steel bar to polish the sharp grooves.

When sharpening your serrated blade, continue to adjust the position of the grinding bar so that the steel bar fills the groove. This in turn results in uniform sharpness.

File away the burrs

The blades on the blade are mostly shavings filed during grinding. To remove these burrs, gently rub the blade against fine sandpaper.

Alternatively, you can run the rod lightly against each glove while exercising great care and caution so that you do not put extreme pressure, which is likely to remove the shavings.

Use an electrically serrated knife tip

If you have a few dollars to spray on the best serrated knife sander, you should consider buying an electric sander for the blade. This sander is not only efficient but also less dull than a steel bar.

The electric sawtooth knife tips have built-in guides that make it easy to set the angle.

When using this grinder for your blades, first read the instructions for use and the manufacturer’s instructions. This will inform you about the steps to follow when sharpening your blade.

Most electric grinders come with a 3-step mechanism, where the last step is polishing and polishing.

Once you have read and understood the working principle, the next thing you need to do is place the blade in the grinding slot.

Pull the full length of the blade through the electric sander 4-5 times for each side. Change sides to paint uniformity and evenness.

The best thing about an electric grinder is that it is a good choice for extremely boring saw blades that are otherwise difficult to grind using a grinding steel.

Since not all serrated blade models are the same, you can adopt different grinding strategies depending on the type of blade you are grinding.


It is not always an easy task to maintain the sharpness of a serrated blade.

Unlike straight edging blades, which you can sharpen in just a few minutes, the saw blades are complex to sharp. A sharply serrated blade cuts easily through food and in clean and uniform cuts.
