Serrated knives have many types with different uses, which are essential for everyday life, for example, a model for cutting cakes, cutting bread, serrated meat knife. So do you know how to sharpen a serrated knife? The following article will show you at least 5 ways to do it.
5 Best Ways to Sharpen A Serrated Knife
1. Sharpening with A Whetstone
If your serrated knife shows rust lines, you need to remove those lines immediately. Just brush the blade with the whetstone carefully and evenly distribute the hand force along the length of the knife. This type of knife is not usually designed with a sharp blade so a flat whetstone is suitable for sharpening it.
2. Sharpening with a Sharpening Rod
This is the most common and arguably the most effective method for sharpening serrated knives. Rod sharpening rods often have a tapered tip for sharpening serrated blades of different sizes.
Step 1: Position the side of your knife with a beveled edge. Serrated knives are generally not the same from both sides. On one side, the face of the blade will continue at the same angle until the edge of the blade. Otherwise, the side of the blade will tilt slightly down just before the serrated edge, forming a bevel. Apply only one sharpening tool to the bevel edge.
Step 2: Place the sharpening rod in a diagonal direction from the edge of the blade from 13-17 degrees. You can use a marker to determine the touchpoint of the sharpening rod and blade. If the sharpening bar rests on the correct bevel of the knife, you’ve done it right.
The diameter of the sharpening rod should be equal to or less than the serrated slot on the blade.
Step 3: Grind each groove on the blade. Sharpen the sharpening bar quickly and decisively in the arc direction to better engage the knife edge. Use your finger to check the sharpness of the knife. If the saw teeth of the knife are of different sizes, adjust the position of the sharpening bar so that the bar just fills the slot.
It is important to sharpen each cog only to its certain width, otherwise, you may damage the blade.
Step 4: Remove grit by scrubbing the blade with fine-grit sandpaper. If you don’t have sandpaper, you can also directly use the sharpening rod to remove the shavings.
Step 5: Sharpen any straight edge of the blade. If your knife only has serrations along part of the blade’s length, sharpen the rest with a whetstone or other sharpening tool. Do not attempt to use the serrated knife sharpener on the straight part of the blade.
3. With a Tri-angle Sharpmaker
Like sharpening rods, tri-angle sharpmakers are designed specifically for serrated knives. Knives with V-shaped grooves are well suited to this sharpener. It includes triangular sharpening rods that allow easy access to individual serrations, while the system itself keeps the angle consistent. The sharpening process is similar to the sharpening rod method described above, except that you rock the edge of the sharpener back and forth along the bevel instead of rotating it.
First, orient the sharpening rods with one of the triangle corners facing the face of the knife you want to sharpen. Next, place the cog closest to the handle towards the end of the sharpening rod. Run the serrated edge of the knife along the sharpening bar making sure to run each serration on the stone. Repeat this process until you feel a ridge protruding on the opposite side, then use the remaining sharpening rod to remove the ridge.
4. With Sandpaper
If you don’t have a sharpening stick, you can make one yourself using sandpaper and a stick/chopstick. Implementation: Wrap sandpaper around the stick, use your fingers to hold the sandpaper, grind carefully and slowly. Use a round stick for circular serrated knives and a square stick for V-grooved knives.
5. With a Square Stone
This is a bit difficult to do. It’s usually done like this: Hold the knife spine steady on a hard surface and tilt the blade so that the chamfer is at the top. Carefully move the thin end of the stone back and forth between the knives for sharpening. You should choose small, thin stones that can get between the grooves of the serrated knife.
How to Sharpen Micro-Serrated Knives?
There are many different tools that can help you sharpen a micro-serrated knife, such as a sharpening rod, a sharpening stone, or a grinder. There are 3 main steps you need to remember when sharpening a micro-serrated knife:
Step 1: Find the bevel of the knife
Finding the bevel face is important for determining the grinding angle.
Step 2: Grinding
Make sure you sharpen the side opposite the bevel – the flat side. This way you won’t smooth out the jagged ends on your blade. You need to be very gentle when sharpening micro-serrated knives because the serrated tips can get caught and broken if you press hard on the sharpener.
Step 3: Test the knife sharpness and polish
For micro-serrated knives, you can feel the sharpness of the knife after sharpening through the burr on the chamfer.
Once the sharpening is done, it’s time to polish the blade. Unlike other knives, micro-serrated products are easy to damage the blade if sharpened and polished improperly. To polish, you place your blade on the cardboard, tilted to the oblique side. Cover the blade with cardboard and pull gently to remove the burrs.
