The benefits of ultrasonic cutting

How does the ultrasonic technology work? 

It all starts with an ultrasonic generator. It receives energy from the battery and converts it into a high-voltage and high-frequency signal. This means, for example, that 12 V makes 900 V and at a certain frequency it passes this voltage on. In order for it to be an ultrasonic generator, the signal must run at a frequency of 20,000 Hz or more.

This signal goes on to the ultrasonic transducer, which is one of the most important parts of ultrasonic cutting. The ultrasonic transducer acts as a kind of converter. Its purpose is to receive a high-frequency electrical signal and convert it into a high-frequency mechanical motion.

And at the end of this process is a booster that acts as an acoustic resonance enhancer. This is traditionally attached to the tip or the blade. In our case, however, we wanted to preserve the design of a traditional knife, so we went without a booster and fixed the blade directly to the transducer. 

Wireless charging

The knife is equipped with a battery and wireless charging, including a wireless charging stand. You are not hindered by the length of a power cord. Simply take the knife with you wherever you need it and place it back into the wireless charger after you finish cutting.
