How to Sharpen Carving Knives for Wooden Gifts
We all know that a sharp knife makes carving wooden gifts much easier and more efficient. However, a truly sharp edge must meet two key criteria. Let’s go over them together!
What does a sharp blade for carving wooden gifts look like?
First, the blade surface should be as reflective as a mirror, allowing you to clearly see reflected text. Second, a polished edge reduces cutting resistance. When looking at the blade with one eye, the edge should appear as an almost invisible line. If you see a reflective white line along the edge, that means it still needs sharpening.
Now that we know what a sharp blade looks like, we have a clear direction for sharpening. Whether you’re using a sharpening stone or sandpaper, the process and technique remain the same. For this guide, we’ll use sandpaper to demonstrate the full sharpening process—from reshaping to refining to polishing. You can apply the relevant steps depending on your knife’s condition.
What’s the purpose of sharpening?
Why do we use different grits of sandpaper? Coarse sandpaper removes material quickly, while finer sandpaper gradually smooths out the sharpening marks left by the previous grit.
Even if a blade looks mirror-polished, under a microscope or magnifying glass, you’ll still see tiny scratch marks. These marks are left by high-grit sandpaper, but they become so fine that they are invisible to the naked eye and undetectable when carving wood. That’s the goal of using progressively finer sandpaper.
For example, if a knife’s edge is chipped, what grit should you start with? Usually, 240-grit is a good starting point. But if the damage is severe and you want to remove material faster, you can start with 180-grit.
How is a knife for carving wooden gifts sharpened?
Simply spray some water on the sandpaper and slide the blade forward until you achieve the desired sharpness. It’s really that simple.
However, the next step is a bit trickier. If your knife has chips or nicks, you’ll need to use a specific technique. Again, spray some water on the sandpaper and press the bevel of the blade flat against the surface. Make sure there’s no visible gap—not even a drop of water should be able to pass through. Then, use your thumb to hold the blade firmly and move it side to side while gradually pushing forward.
Throughout the process, keep your thumb firmly pressed against the blade, moving it slowly forward while creating consistent sharpening marks. Repeat this step continuously.
Now, take a closer look at your blade. We’ve just sharpened the bevel, but now there’s a burr on the other side. If you gently run your fingertip along the edge, you’ll feel a slight resistance. If the burr is consistent along the entire edge, that means it’s time to sharpen the other side using the same technique.
When a burr forms on the second side, it’s time to switch to a finer grit sandpaper. The general rule for selecting the next grit is to double the current grit size. For example, if you’re using 240-grit, switch to 480-grit next. If you’re at 480-grit, move up to 800-grit.
Now, let’s review the entire sharpening process:
- Spray water on the sandpaper.
- Lay the bevel flat against the sandpaper.
- Hold the knife firmly with your thumb and move it side to side while gradually pushing forward.
- Check the edge—are the sharpening marks even across the entire bevel? If not, continue sharpening.
- Feel for a burr on the other side. If you find one, flip the knife and repeat the process.
Once the burr forms along the entire edge, switch to the next finer grit and continue sharpening. Repeat this process until both bevels are completely smooth. Based on experience, working up to 2000-grit sandpaper usually gives great results.
Finally, use a strop to polish the blade. Press the bevel flat against the strop, move the blade forward, then lift it at the end of each stroke. Repeat 8-10 times.
