Powered by Ultrasonic Precision
Thanks to high-frequency micro-vibrations, powered by ultrasonic energy, this knife ranks among the most precise and powerful tools for slicing, cutting, and chopping a wide range of food materials.

What makes ultrasonic cutting so effective?
-
Ultrasonic vibrations greatly reduce food sticking to the blade, ensuring smooth and uniform cuts.
-
Even dense or crusty foods are easier to cut due to increased cutting force.
-
Precise slicing helps retain moisture, nutrients, and structure.
-
Perfect for layered dishes and pastries – cuts through without shifting or squashing layers.
-
Ideal for delicate, crumbly items that typically fall apart with standard knives.
Maximum cutting performance, minimum effort.
Swappable Blades
Need a different blade for a specific task? The modular system allows you to easily swap blades depending on your cutting needs – quick, simple, and tool-free.
