Knives come in various shapes and sizes, each serving a unique purpose in everyday kitchen tasks.
One type is the serrated knife. This saw-toothed knife easily cuts through tough objects and requires very little maintenance.
As the title says, this guide is all about serrated knives and how to sharpen them!
What Is a Serrated Knife?
A serrated knife has a blade with a saw-like edge on one side. The serrated design allows it to easily cut through tough, thick-textured materials like crusty bread loaves.
The toothed, saw-like design of the serrated knife gives it an advantage over plain knives. Serrations let the user cut tough materials at sharper angles with fewer contact points. This sharp-angled approach with minimal contact increases the applied pressure, resulting in fast and precise cuts.
Finally, serrated knives last longer than their counterparts in terms of sharpness and maintenance. And that brings us to this part.
What Causes Knives to Become Dull?
As stated earlier, serrated knives tend to stay sharp longer than plain knives. However, they can still become dull for any of the following reasons:
Using the knife on glass or stone surfaces. The friction between the blade’s metal and stone changes the shape of the serrations and can significantly reduce the knife’s cutting ability.
Putting it in the dishwasher where it rattles against other utensils can affect its sharpness.
Using it improperly, such as using the knife as a screwdriver, damages the tip and causes dullness.
Can Serrated Knives Be Sharpened?
As mentioned earlier, serrated knives apply maximum pressure at fewer contact points, which reduces friction. Therefore, they usually require minimal maintenance to stay sharp.
However, they can still become dull, and there are various ways to sharpen them. Common methods include using diamond sharpeners, ceramic honing rods, electric serrated knife sharpeners, motorized knife sharpeners, and more.
What Type of Knife Sharpener Is Best for Serrated Knives?
Every serrated knife has a unique serration pattern. One knife might have 33 serrations, while another might have fewer or more. It all depends on your choice.
Using any of the above-mentioned serrated knife sharpeners requires sharpening each serration individually. That’s why many people prefer to leave the task to professionals.
The best way to sharpen a serrated knife is by using a diamond-tapered knife sharpener or an electric serrated knife sharpener, both of which are readily available to professional service providers.
What Is Sharpening Steel?
Sharpening steel, also known as honing steel, comes in various forms, all serving the same purpose: sharpening the knife. Some are made entirely of steel, ceramic, or even diamond-coated steel.
Technically, a sharpening steel is not a serrated knife sharpener. It is used to realign the microscopic curls in the blade that develop over time.
There Are Many Great Knife Sharpeners Available for Your Serrated Knives!
The market is flooded with products claiming to be the best serrated knife sharpener, making it hard to decide which one is right for you and your knife. Here’s a simple way to approach that dilemma:
Prioritize ease of use when choosing a serrated knife sharpener. An electric serrated knife sharpener is intended for professional use, while a sharpening steel is handy for the average household user.
How to Sharpen a Serrated Knife
Depending on your skill level, any serrated knife sharpener can do the job. Moreover, there is no fully automatic serrated knife sharpener. Even motorized sharpeners require manual handling, so there is always a risk of injury. That’s why it’s better to leave the task to a professional.
For educational purposes, let’s explore some methods to sharpen a serrated knife:
Tools Needed to Sharpen a Serrated Knife
First things first, what tools might you need to sharpen a serrated knife?
But before we get to that, it’s important to clarify that there is no all-in-one serrated knife sharpener.
Each tool is designed to meet specific users and their needs. These can range from simple sharpening steels to complex electric serrated knife sharpeners.
3 Tips for Sharpening Serrated Knives
Serrated knives can be easily sharpened by following a simple standard operating procedure (SOP). Some actions should be strictly avoided, while others are considered good practice, all of which are discussed here:
- Different shapes and sizes of serrated knives require different sharpening tools. Choosing the right equipment can make a big difference. In most cases, a standard sharpening rod can cover a wide range of serrated knives.
-
The side of the knife and the angle at which it is sharpened play a significant role in proper procedures.
- Only sharpen the beveled side of the serrated knife. Sharpening the other side can damage the blade’s integrity.
- To avoid damaging the serrations, follow the angle of the gullet, usually between 10 and 30 degrees.
- Knife sharpening requires manual handling, which calls for safe gripping techniques. To avoid mishaps, from minor inconveniences to serious accidents, use a vice grip to secure the knife in place.
A Guide to Sharpening Your Serrated Bread Knives at Home
The DIY method of serrated knife sharpening uses honing rods. As mentioned earlier, sharpening a serrated knife can be tricky because each serration on the beveled side needs individual attention.
Here’s how to use a honing rod as a serrated knife sharpener by yourself:
- Among all types of sharpening rods, diamond-coated steel rods give the best results, closely followed by ceramic rods.
- No matter the material of your sharpening rod, it will have varying thickness. This variable thickness allows the rod to fit different shapes and sizes of serrations.
- Find the appropriate width for your serrated knife on the honing rod. Then place that part of the rod between the serrations and drag it through.
- Maintain a 10-30 degree angle and continue dragging the rod away from the blade. Dragging the rod away from the knife helps prevent injury.
- For best results, stroke each serration at least 4-5 times.
- After finishing the beveled side, flip the knife and stroke the flat edge a couple of times using a regular sharpening stone.
- Wash away the burr and dry the knife promptly. That’s all there is to DIY serrated knife sharpening.
How to Sharpen a Serrated Knife with an Electric Sharpener
Continued use of an electric serrated knife sharpener risks damaging the serrations. But there’s no denying it makes the process less labor-intensive. Here’s how to use an electric serrated knife sharpener:
- Clean the blade and select the stage of the electric sharpener you want to use. Usually, setting it to a fine stage is enough to properly hone the blade.
-
Once you’ve selected a particular stage on the sharpener, run the blade through it four times in the following manner:
- While holding it down, pass the blade from the heel of the knife to its tip. Make sure that the serrations are in contact with the sharpener’s wheel. Run through both sides of the serration.
- Repeat the process if the knife hasn’t reached the desired level of sharpness. However, if the sharpness meets your expectations, stop the process, and rinse the knife with water before use.
- That’s it. Your serrated knife is now as good as new.
Frequently Asked Questions
1. Can I Sharpen A Serrated Slicer Or Serrated Electric Knife?
A serrated slicer, or the electric version of serrated knives, can be sharpened using the same techniques as mentioned above.
A serrated electric knife should be unplugged from the power source. Then, the handle and the blade should be removed from the motor and sharpened accordingly.
2. How Can I Sharpen A Serrated Knife Without Any Special Tools?
The complex design of serrated knives requires the use of special tools like honing rods. Despite that, serrated knives can still be sharpened using something as ordinary as an old coffee mug.
The bottom depression of the cup and the surrounding rim together serve as an excellent knife sharpener. Its mechanics are similar to sharpening rods: the serration is placed on the rough bottom and stroked at least 5 times to ensure proper sharpness.
3. What Other Steps Can I Take To Ensure My Serrated Knife Stays Sharp As Long As Possible?
Serrated knives already have a longer lifespan than straight-edged knives. Their longevity can be further extended by avoiding the bad knife practices mentioned in the article. For example, they shouldn’t be placed in the dishwasher with other items.
Frequent exposure to water should also be avoided at all costs. And the knife must not be used for anything other than cutting.
Lastly, the blade becomes weakened and dull after every fall, so a magnetic knife holder might be useful.
4. Should You Use An Electric Knife Sharpener To Sharpen A Serrated Blade?
The blades of a serrated knife do get damaged if they’re frequently sharpened using electric sharpeners. Moreover, the serrations might break or become uneven. Increased burr or metal loss also weakens the blade.
Ideally, serrated knives should only be sharpened when they are very dull. Even then, it’s better to use a sharpening rod rather than an electric serrated knife sharpener.
5. Can I Use a Whetstone to Sharpen My Serrated Knife?
A whetstone offers one of the easiest ways to sharpen serrated knives, but the process is very time-consuming and labor-intensive. Its mechanics are similar to those of a sharpening rod.
6. Can You Sharpen a Cheap Serrated Knife?
As the name implies, cheap serrated knives are made by compromising blade quality. Electric knife sharpeners already damage the blade’s integrity, so a cheaper knife won’t withstand repeated sharpening.
7. What Is a Serrated Knife Good For?
Serrated knives excel at cutting through tough materials. In the kitchen, they are used to make quick, precise cuts on crusty bread, tomatoes, and large pieces of meat. A general rule is that serrated knives are best for cutting objects with a tough exterior and soft interior.
8. Is a Serrated Knife Better for Self-Defense?
Their use as a self-defense weapon is debatable. Although they can cause serious wounds, experts argue they may get caught in the attacker’s clothing, making them ineffective.
On the other hand, a serrated knife can easily cut through jackets or other tough materials. In short, serrated knives are only effective if you can get past the clothing and stab directly into exposed flesh.
Conclusion
Serrated knives are essential kitchen tools if you want to make cutting easier. The serrations let you cut through tough items faster and with unmatched precision. These knives require little maintenance and usually outperform straight-edged knives in sharpness, durability, and more!
In the long run, even serrated knives need sharpening. There are many techniques available, from DIY methods to professional services. Using a sharpening rod is labor-intensive but preserves the blade’s integrity. However, frequent use of electric knife sharpeners can shorten its lifespan.
Now, with all this knowledge at your fingertips, you’re ready to decide whether to buy a serrated knife or have one sharpened!
