How to Sharpen a Serrated Knife Using the DMT Serrated Knife Sharpener

DMT Serrated Knife SharpenerSharpening a serrated knife is much different than sharpening a traditional straight blade. Each individual serration will need to be sharpened separately. Because a serrated knife functions like a saw, it can often still cut when dull. However when dull, it will tear or shred rather than cutting smoothly. To restore a sharp edge that will cut smoothly, we recommend using the DMT Serrated Knife Sharpener. See below for complete instructions.

Instructions:

1. To begin, select the proper grit size of DMT Serrated Knife Sharpener (available in extra-fine, fine, coarse and ceramic). For most knives the fine grit will provide a good cutting edge and will sharpen at a good rate. The coarse grit is optional for a faster sharpening rate on very dull serrated knives. The extra-fine and ceramic grits will provide a polished edge.

2. Match the diameter of the cone on the DMT Serrated Knife Sharpener to the size of the serration or gullet on your knife. Note: The serrated knife sharpener is tapered to match wide and narrow serrations.

3. With the sharpener in one hand and the knife in the other, use a few short, light, back and forth strokes to sharpen the beveled edge of each individual serration. Keep the sharpener perpendicular to the beveled edge. After a few strokes, feel for a burr on the backside of the knife. Once you can feel the burr, move on to the next serration.

4. Once all the serrations are sharpened, flip the knife over and lightly grind the burr off with a smooth, light flat stroke.

5. Your knife should be properly sharpened and ready to cut.

Thanks John, I am so glad to be working with people who know their products and how to use them. You have a very informative and well laid out website and I learned a lot. It was a rainy Sunday and I watched every video and read through each article. The information you provided was very helpful in teaching technique and helping me decide what to buy. Also your products are so well thought out, that no matter what stone you prefer (oil, water or diamond), there is a nice package available for a beginner. All of the products you put together each had their own advantages and believe me, each one spent some time in the shopping cart until I made my final decision.
