About us
We’re a company built around the technology of sound, frequency, and vibration. We design and manufacture wireless ultrasonic knives, cutters, and have more products in development based on this same principle.
The first idea for an ultrasonic kitchen knife came to us back in 2017. Since 2020, we’ve been fully focused on developing and producing this technology—designing, testing, and refining. In 2023 and 2024, we successfully completed two Kickstarter campaigns, bringing our products to customers around the world. We’ve also presented our knives and cutters at major exhibitions like IFA in Berlin, Technologie in Prague, the Geneva Innovations show, and IBA in Germany.
We believe this technology has huge potential—in the kitchen, in industry, and in everyday use. Our goal is to keep developing it, making it better, and bringing it to more people. That’s what we’re working on every day.

FAQ
How does the ultrasonic knife work?
The blade vibrates at ultrasonic frequency, reducing friction and making cutting smoother and easier.
What materials can it cut?
Food, plastics, foam, rubber, textiles, leather and many other soft materials depending on the blade type.
Is it safe to use?
Yes. The blade itself does not become dangerously hot and the device includes multiple safety protections.
Can I replace the blades?
Yes. The blades are replaceable and different blade types are available.
Where are the knives manufactured?
Our ultrasonic knives are manufactured in Europe.
Do you ship worldwide?
Yes. We ship worldwide using express shipping services such as FedEx.
Can ultrasonic vibration damage food?
No. Ultrasonic vibration mainly reduces friction during cutting and does not negatively affect normal food use.
What is the difference between the 45W and 70W version?
The 70W version provides stronger cutting performance and faster heating, while the 45W version offers longer battery life.
Can I customize my knife?
Yes. You can choose blade type, color, charging option, engraving and more in our configurator.
How long does the battery last?
Approximately 30 - 45 minutes of continuous cutting depending on the material and power version.
