From the tip of your sharpener, move to the edge of the blade. Also, make sure that you’re using it on the side and on the flatter part of the ulu’s blade. 

3. Repeat the Process 

Continue on the second step. After some time, you’ll see a shine on the blade. However, you can still continue to sharpen the blade as long as you want. 

4. Remove the Burrs

After you’re done sharpening one side, it’s time to remove the burrs. If you can remove the burrs on your blade, then you can provide the sharpest edge as well.

Whetstones are excellent sharpeners. They’re easy to purchase and really simple to use. In fact, even your ancestors used these stones decades ago. So, let’s look at the process: 

1. Use a Sturdy Surface 

It’s crucial that you manage a sturdy surface whenever you’re going to sharpen an ulu using whetstones. You really don’t want a wobbly surface because it can cause accidents. 

Besides, a sturdy surface will allow you to maintain a constant angle at the time of sharpening your ulu. 

2. Clamp the Blade 

First, clamp the blade in the sturdy surface. However, make sure that you place the ulu far away from your hands so that they don’t cut you accidentally. 

3. Start Sharpening the Blades 

After you place the ulu and secure it to the clamp, it’s time to sharpen it. Firstly, use the whetstone on the blades in one direction. In addition to this, make sure you’re not pushing the blade too hard 

However, make sure that you aren’t sharpening the ulu at an awkward angle. You need to make a constant angle on the curve. Also, make sure you’re sharpening it at a lower angle. This is because the lower the angle, the sharper the blade will be. 

4. Sharp at One Direction

Most of the ulus come with a single bevel. So, you need to sharpen it gently. Also, you need to make sure that you sharp in one direction at the start. 

This is because when manufacturers make this tool, they sharpen it in a direction only. Thus, you need to follow that technique. After sharpening the blades for some time, it’ll look shiny which will indicate that it’s ready. 

5. Remove burrs on the Other Side

After you’re done sharpening the ulu using a whetstone on one side, it’ll look shiny. However, if you notice the other side, you’ll see that there are small burrs on it. 

So, how can you remove the burrs? 

It’s easy to remove them. You can just put a few light strokes on that side using the whetstone and it’ll do the trick.

· They can provide sharp edges.
