All things considered, it consequently re-profiles American and European style knives to an ultra-sharp 15-degree angle cutting edge.

What is Trizor XV?

It distinctively makes a 15-degree triple-bevel curve-shaped edge that opposes dulling longer than a “V” shaped edge. And it delivers a burr free triple-bevel fine edge. The Trizor XV technology also helps to extend the life of the knife blades.

It does this by forcing a 3-step arch-shape edge grinding, first to around 25 degrees, then 22 degrees, and lastly 15 degrees. This guarantees the blade remains more honed for a more extended timeframe, an aspect many consumers will fall in love with.

Using The Sharpener

You can catch some guides on how to handle the unit correctly and safely, and tips to maximize the sharpening process.

The 3-stage consists of 100% diamond abrasives with flexible stropping disks in the third stage.

The first stage welcomes you to sharpen very dull American and European style knives. Prepare to start with a few strokes on each alternating slot. The bulk of the metal are removed at this stage.

No worries. Move to next stage.

Repeat the same number of strokes at stage 2. This time a second bevel is created on the blade.

Then move on to the final stage to polish and hone the knife to hair-splitting sharpness. Finally you’ll get a well-polished 15-degree style knife.

Clean the knife and test it on paper and tomatoes. See and feel the difference.

You may need some practices to optimize the sharpness according to the dullness of the knife. Add or reduce the number of strokes accordingly.

If you have Japanese knives, skip stage 1 and start with stage 2. And for serrated knife, go to stage 3 will do the trick.

More than Just Grinding

To get a smooth and clean edge with hair-splitting sharpness, it has more to do with just grinding the blade.

The built-in high precision and flexible spring guides give precise control of the reshaping/honing during the sharpening process. It achieves this accomplishment by keeping an even pressure point all through each of the three stages. The blade has no chance to wobble, thus resulting in razor sharp edge.

Many brands can’t match up to this technology. The America’s Test Kitchen did a test on this and observed all sharpened knives under a powerful microscope, many had ragged edges.

Only the knife that was sharpened by Trizor XV sharpener came out smooth and sharp. ATK endorsed it as the best electric knife sharpener in their knife sharpener test.

The Benefits of 15-Degree Angle Blade

The 15-degree edge cuts more effectively than a conventional 20-degree angle edge. The truth fact is, the more slender the edge the less force it takes to cut and the simpler the blade is to control. Also, this thinner blade edge will last longer in view of its one of a kind triple-bevel Trizor XV edge technology by Chef’s Choice.
