1. Choose the side of your serrated knife with a beveled edge

The knife’s serrations are only located on one side of your knife. it has a part called a bevel. You need to sharpen the other side just like any other straight edge. So, apply your rod only on the beveled side.

2. Put the sharpening rod in each serrated gullet

 Grasp your serrated edge and let the tip of the knife away from you. Put the ceramic sharpening rod in each serration. Adjust the angle of the sharpening steel with each gullet so that it resembles the original sharpening angle of 13 to 17 degrees.

  • You can use a marker as a guide. If you remove the marker tag while passing the rod, then you are on the right track.
3. Match the sharpening steel with the diameter of the serration.

If you have a tapered sharpening rod, fit the cone-rod with the serration. As a result, the diameter of the tapers is the same size as the serration. And don’t make the serration wide by choosing a different diameter. 

4. Wear gloves for your own safety.

 Wear gloves to avoid hurting yourself as the sharpener may tear your finger

5. Sharpen the first serration

 Push the cone-rod through the serration with gentle moving, typically for a couple of strokes. You only have to push in one direction away from the edge of the blade until you reach the spine of the rod.

 I do not recommend passing the rod back and forth. Instead, you can rotate or flip the sharpening rod for a consistent sharpening. Draw the cone-rod slowly away from the blade each time to protect yourself from the edge of the knife.

 After doing several strokes, you will get metal shavings, which are called “burr.” Pass the back of the knife against a leather strop, which will eliminate any burr. Then your serrated blade can provide you with the perfect slices.


Such a method that you will work on manually will sharpen a serrated knife perfectly. However, this knife sharpener tool needs effort.

1. Place the specific triangle sharpening steel

 Set your Sharp maker apparatus on any cutting board or hard ground. Put the specific triangular rods in the holders of the sharp maker, and you will get the job done. 

  • Do not forget to expose the triangular point of the rods to the serrated gullet side of the knife. Also, locate the flat side of the rods on the backside to be for the plain straight edge side of the blade.
2. Choose the right angle and pass the knife.

 Slide your serrated knife in a gentle way across the rods of the Spyderco sharp maker. Choose a slight angle and pass it several times for each face of your knife. And try to be much slower on the serrated edge so that you will not damage the gullets.

3. Use the chock-up technique

Choke-up the dullest parts of your serrated edge to wrap the whole side.

4. Pass it for several strokes.

Continue repeating this process for 5 or 6 strokes on each side of your edge. Do not forget to set an angle for your serrated edge that matches the rod just as the first secure method.

5. Eliminate the burrs.

Remove the burrs by angling the edged blade a little bit far. Make sure it still won’t damage the backside of the knife by scratching it.

6. Use a leather strop to move away from all the remaining burrs.
