Truly Helpful
"I wasn’t sure about this, but I’ve tried it on several knives so far and it has worked very well. The magnets are strong enough for small knives and the block has feet that stick very firmly to flat surfaces. Great little kit for anyone that wants sharp knives but no time for whetstones!"
Knives sharper than the day I bought them!
Most of my knives got ruined by cheap sharpeners, so the first one took about half an hour. To my surprise, it worked—and the knife is sharper than the day I bought it.
Highly Effective, Works Instantly
I’ve tried all gadgets and whetstones—they were useless and hard to use. This actually works: a blunt knife could shave a cherry tomato after 10 minutes. Amazing!Frequently Asked Questions
❓ How long does it take to sharpen a knife?
❓ How long does it take to sharpen a knife?
Sharpening time can vary the first time you use the Novara, depending on your knife’s condition and steel quality. On average, it takes about 5 minutes.
During the first use, the blade needs to form the correct 15° or 20° sharpening angle. Once that edge is established, future touch-ups are fast and easy—just a few smooth rolls back and forth thanks to the consistent grinding angle.
❓ How do I clean the diamond sharpening discs?
❓ How do I clean the diamond sharpening discs?
To clean the diamond discs, simply wipe away any grinding residue with a damp cloth. That’s all it takes to keep them performing at their best.
❓ How do I sharpen knives that are taller than the sharpener?
❓ How do I sharpen knives that are taller than the sharpener?
For wider or taller blades where the cutting edge sits above the grinding disc, simply raise the sharpener using a thick cutting board. This ensures the blade edge stays within the radius of the diamond disc for proper contact and effective sharpening.
