Learn to keep your knives keen with a sharpening rod or other tools
Download Article
Serrated knives are specially designed to saw and grind through food, and as a specialized tool, they require special maintenance. Rather than using a regular sharpening stone, reach for a tapered sharpening rod, and work tooth by tooth. [1] X Research source We’ll show you how to do just that, as well as other options to keep your keen kitchen cutter razor-sharp. We’ll also show you how to properly store and maintain it so that it keeps its edge longer.
Things You Should Know
- Hold the sharpening rod in your dominant hand and position it at a 15-20-degree angle against one of the knife’s serrated “scallops,” so that it rests in the curve.
- Move the rod back and forth across each serration, giving 10-20 quick, short strokes each time, until a small burr or prick forms on the other side of the blade.
- Run the opposite side of the blade flat along the rod 2-3 times to remove the burr, then wash and dry the knife to remove any shavings.
Steps
-
Locate the beveled side of your blade and find a sharpening rod. Unlike other knives, serrated knives tend to be flat on one side of the blade and beveled into grooves on the other. This beveled side of the knife is the side we’ll be working with. Also unlike other knives, serrated knives require a sharpening rod to sharpen, which are often tapered to accommodate many sizes of serration. [2] X Research source
- A ceramic sharpening rod is great for giving a blade a little TLC, but if your serrated knife is particularly dull, use a diamond rod , which will restore its edge.
- If you don’t have a sharpening rod, wrap and tape a bit of emery cloth around a wooden dowel to use instead.
-
Align the rod with one of the serrations (or "scallops"). Hold the rod in your dominant hand, perpendicular to the knife, and rest it within one of the knife’s serrations—start with the one closest to the knife’s handle. Position the rod so that it’s aligned with the angle of the serration’s bevel, usually about 15-20 degrees. [3] X Research source If your sharpening rod is tapered, position it in the serration at the point where the rod's diameter is about the same size as the serration.
- If the knife also has a straight edge portion, the bevels are usually ground to the same angle—about 20 to 25 degrees. [4] X Research source
- To get a better guide for your angle, draw on the beveled side of the serrations with a permanent marker. You'll know you're hitting them at the right angle if the marker is totally removed with 1-2 strokes.

Move the rod back and forth 10-20 times to sharpen each serration. While applying very light pressure to the blade, run the sharpening rod back and forth within the first serration to sharpen it. Repeat 10-20 short strokes to make sure the serration is adequately honed. Then, do the same for the next serration, and keep going until each serration is sharpened. [5] X Research source The serration is sharpened when you can feel a burr or prick on the opposite, flat side of the blade.
- Or, move the knife itself along the rod, rather than moving the rod along the knife. Some chefs stand the rod on-end and make a downward slicing motion with the knife. It’s up to you! [6] X Research source
- Remember to keep a tapered rod’s diameter matched with the size of the serration to avoid enlarging the scallop.
-
File away all the burrs with your sharpening rod. The burrs are the metal shavings that you filed off when sharpening the blade. To remove them, place the flat, un-beveled side of the knife flat against the rod, and run the rod 2-3 times along the entire length of the blade. [7] X Research source
- Or, use a regular whetstone or even some fine-grit sandpaper for this step, instead of the sharpening rod. The end result is the same.
-
Sharpen any straight-edged portion of the blade. If your knife is only serrated along a part of the blade's length, sharpen the remaining length with a whetstone or other sharpening tool. Don't attempt to use the serrated knife sharpener on the straight portion of the blade.
- When you’re done, wash the knife with warm water and dish soap to remove any shavings.

Use a triangle-shaped sharpener. A triangle-shaped sharpener is compatible with many different blades, including serrated knives, and works much the same way as a traditional sharpening rod. These sharpeners have the added benefit of defining the angle for you—just hold the knife straight and drag it along the tilted rods. [8] X Research source Due to the shape, they tend to work best on knives with V-shaped gullets.
-
Try a specialty electric serrated knife sharpener. If you’d rather not fuss with a sharpening rod, or just want to save a bit of time, opt for an electric serrated knife sharpener . These are different from regular electric knife sharpeners, and are specially designed to work with the serrated grooves of your knife. Typically, turn on the sharpener and drag the blade of the knife through the designated slot of the sharpener. [9] X Research source
- These devices vary widely in design and function, so consult your sharpener’s manual for more specific instructions.
-
Hire a professional knife sharpener. If your knives are in especially poor condition, or you just want to sidestep the work, a professional knife sharpener will have your blades in tip-condition—for a fee (usually several dollars per knife). They often provide their services at local farmer’s markets, or you might take your knives into a nearby cutlery store to have them serviced. [10] X Research source
-
Use the corner of a square stone to sharpen the serrations. This is a difficult and unreliable last resort, but it is possible. Hold the knife spine securely against a hard surface and tilt the blade so the beveled edge is on top. Bring the corner of the sharpening stone to the serrated edge and use it to sharpen each serration, as you would with a sharpening rod, rocking it back and forth to cover the full area of each serration.

Wash your knives by hand to maintain their edges. The harsh detergents, heat, and contact with other dishware prematurely dull your sharp knives. Instead, wash your serrated knives by hand with warm water, dish soap, and a sponge. Point the blade away from you, and work slowly to avoid injury. [12] X Research source When you’re done, give them a rinse under warm water and dry them with a soft towel to prevent rust. [13] X Research source
- If there’s food dried to your knife, let it soak in warm water for 1-2 minutes to loosen the residue.
-
Use a cutting board to keep the serrations sharp. Cutting something directly on your counter or any other hard surface dulls the blade of the knife when it strikes that surface. Instead, always use a cutting board to minimize wear. But the material of the cutting board matters, too. Maple is a relatively soft wood that’s easy on your edges, but materials like bamboo are extremely hard and rough on those serrated teeth. [14] X Research source
-
Store the knife in a knife block rather than loose in a drawer. Tossing your knives in a loose drawer runs the risk of dulling or even chipping them against other cutlery. Instead, slot your knives into a knife block or an in-drawer block , or hang them from a magnetic knife strip to preserve their blades. You might also slip them into blade guard sleeves if you don’t have other storage options, or are taking your knives on the road. [15] X Research source

QuestionWhat if the serrations are really small?Community AnswerA narrow triangular tool is your best bet. If you can't find one that works, focus on sharpening the tip of the edge rather than the scallops. The result won't be perfect, but it can still make a big difference on a dull knife. If it's important to get the best quality, send your knives to a professional.

QuestionWhat are safe secure storage procedure for knives?Community AnswerThe best place for kitchen knives is in a knife block. It keeps the edges safe so they don't become dull from contact with other kitchen utensils, and it keeps your hands safe from getting cut when you reach into a drawer filled with random utensils. Make sure your knives are dry before inserting them into the block to avoid unnecessary rusting. The knife block's position is all up to you, but if you are worried about children you can move it to the back of the counter space or in a cabinet with child locks. Another method of storage is a magnetic strip mounted on the wall. It allows for easy access, but keeps the knives well out of reach of small children.

- Sharpening each serration individually does take a bit of time, but use this opportunity to practice and perfect your technique.Thanks
- Secure the knife in a vice to make the job easier and safer. This is more important if you are using a homemade emery cloth tool, since your finger will be positioned close to the sharp edge.Thanks
