This knife needs a battery

This knife vibrates 30,000 times a minute and is supposed to cut better. That's the promise of the company "Seattle Ultrasonics". You can order the ultrasonic cutter now for 310 francs.

In the 1990s, my mum used to get out an electric knife that resembled a hedge trimmer for the Christmas roast. The idea was to cut thin slices as evenly as possible. It never really worked, the slices were neither even nor particularly thin.

Now there is another revolutionary «» technology that promises effortless slicing. At first glance, the C-200 Ultrasonic from «Seattle Ultrasonics» is a normal kitchen knife. However, the handle contains a rechargeable battery and piezoelectric ceramic crystals that cause the blade to vibrate. The blade vibrates at 30,000 vibrations per minute while the handle remains stable.

Ultrasharp even without ultrasound

The knife should be sharp and remain sharp even without ultrasound. This is ensured by triple-folded AUS-10 steel from Japan. You can charge the knife via USB-C or with a wireless charger, which also serves as a magnetic holder and is optionally available for 113 francs or 119 euros.

The first knives are already on sale, but you can get one for 310 francs or 329 euros on the manufacturer's website. A bundle with charger and knife is also available there.

Whether we will include the C-200 Ultrasonic on sale at a later date is still being clarified.

When I flew the family nest over 15 years ago, I suddenly had to cook for myself. But it wasn’t long until this necessity became a virtue. Today, rattling those pots and pans is a fundamental part of my life. I’m a true foodie and devour everything from junk food to star-awarded cuisine. Literally. I eat way too fast.
