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.

Technical data

Behind the scenes

Test video. Demontration of ultrasonic cutting on 4 different types of materials (paper, cardboard, PVC, Plexiglass).

Test video / Difference Between Standard and Ultrasonic Cutting.

For a clearer demonstration, we’ve removed the blade from the handle, leaving it wobbly and unstable. Even light pressure applied with paper can easily topple it.

 To better showcase the difference between standard and ultrasonic cutting, we conducted tests using a blade that isn’t very sharp.Then you can see how ultrasonic technology increase cutting properties.

What phase are we in and what 
are we waiting for? 

After concluding our Kickstarter campaign, we immediately began working on incorporating your feedback into our product. We can now confirm that we have successfully introduced replaceable batteries for the knife, a new type of charging station, and replaceable blades.

We took into account the safety and horizontal charging of the knife. Therefore, we created a second type of charging station in the style of a tanto stand:

And finally, we have developed a system for replaceable blades.

Currently, the product is undergoing certification and the first batch is being prepared for production.

About us

Hey, I’m Willy, the founder of 369Sonic. I believe that there is much greater potential behind sound, vibrations and frequencies than our world has discovered so far. I am fascinated by the power of sound and all its myriad uses. Thus, I have delved into exploring and finding ways to use this power positively and beneficially for people. The ultrasonic knives are just the beginning of our journey.  

Notes:

* In the video and text we state that the knife is 36 times sharper that a standard kitchen knife. This was based on our test where we used a standard / common kitchen knife and compared it in a cutting test to our ultrasonic knife. We used a pt50a sharp electronic tester, which measures the weight / strength exerted to cut a synthetic wire. * In the video and text we state that it is patented technology. Actually, patent application have been submitted to the patent office.
