Scott’s Kitchen Tips: How to sharpen a knife

Written By Scott Joseph On November 23, 2020

Trizor 15

I’ve mentioned before that my main knife is the Wüsthof 8-inch chef’s knife, which I really like. It isn’t cheap but it lasts forever.

But even well-made expensive knives have to be sharpened now and then. A professional knife sharpener is great, but it isn’t always convenient to take your knives to a sharpener’s shop, and besides, they need to be sharpened more often than that.

I could never get the hang of using a sharpening stone because you have to keep the knife at a precise angle. Not easy to do.

But I’ve found a home knife sharpener that I really love and is easy to use. I’m never more than a few minutes from turning a dull knife to a sharp knife.

It’s the Trizor 15 from Chef’sChoice. And by the way, I had another Chef’s Choice sharpener years ago that didn’t work very well. This one, though, is terrific. Watch the video to see it in action.

The 15 of its name is significant. It refers to the preferred cutting angle of a knife’s blade. Japanese knife makers pioneered this style of blade, and even western knife makers that used to produce knives with a 20-degree angle have started to follow suit.

My Wüsthof is old enough that it was made with a 20-degree blade. But the cool thing about the Trizor 15 is that it can convert a 20-degree blade to a 15-degree blade.

That’s what the first two slots of the sharpener are for. Once you’ve converted the blade, you never have to use those slots again.

For regular sharpening, the second and third sets of sharpening slots will do the trick.

You first run the blade slowly through the second set of slots, alternating for both sides of the blade. The Trizor has spring-loaded slots that guide the knife at the correct angle. You do this until you can feel a burr on the blade.

Then you run the knife through the third set of slots, again alternating, three times each side slowly, then twice more quickly.

And that’s all it takes to sharpen the knife. And it works on serrated blades, too.

It’s really a pleasure to work with a sharp knife. With the Trizor XV you’ll always have one. It would make a great gift for someone who loves to cook and chop.
