How to Sharpen a Scandi Grind Knife

For a long time I didn't know how to sharpen a knife. My biggest fear was holding the right angle. That's a real worry when you're about to spend good money on a knife. If that's you, I've been there.
What got me past it was a short video from Roselli. Roselli's owner, Pasi Helin, sits by a campfire with a diamond sharpener and brings a knife back in a couple of minutes. I watched it years ago, and it's what taught me.
What you need
A diamond plate. That's all. You don't need a strop, a soaked stone or a bench.
We stock three: a pocket plate, and two in leather sheaths, one plain and one with a clip.
In the video he's sharpening one of Roselli's Ultra High Carbon (UHC) knives, like the UHC Hunting Knife, and he says that steel needs a diamond sharpener.
The steps
- Hold the diamond plate steady in one hand.
- Lay the blade against it and look at where the edge meets the plate. You'll see a thin shadow in the gap.
- Tilt the blade until that shadow disappears. That's your angle.
- Make small, gentle circles with light pressure. Small movements keep you on the angle.
- Feel the other side of the edge. When there's a slight burr, switch sides and do the same.
- Finish with a few very light passes on each side, tilted up just a little more, to take the burr off.
- Test it carefully on a fingernail. If the edge catches, it's sharp.
One thing about the wide bevel
These knives have a wide bevel on each side, and it's tempting to lay that flat on the stone. Don't. There's a small second bevel right at the edge, and that's the part you're sharpening. The shadow trick finds it for you.
If you'd rather not sharpen
That's fine. A friend, a family member or a shop can do it for you. Roselli will also sharpen any of their knives at their shop in Finland, but you pay shipping both ways.
