Slice Through Anything? My Hands-On With Seattle Ultrasonics' 30,000 Hz Knife at CES 2026
I put Seattle Ultrasonics' revolutionary ultrasonic knife, vibrating at 30,000 times per second, to the test at CES 2026. Is this pricey blade the future of cutting, or just a buzz?
TL;DR: Seattle Ultrasonics unveiled its groundbreaking ultrasonic knife at CES 2026, promising unparalleled cutting precision with 30,000 vibrations per second. While its performance on delicate and challenging foods is genuinely impressive, its premium price point suggests it's a specialized tool for culinary professionals and high-end enthusiasts rather than an everyday kitchen staple.
What's New
CES 2026 is always a hotbed for innovation, and this year, one particular gadget truly cut through the noise: Seattle Ultrasonics' much-anticipated ultrasonic knife. Last year, the company teased the world with the concept of a blade that doesn't just slice, but vibrates its way through food. This week, we got to experience it firsthand, and the reality lives up to the futuristic hype. Forget your traditional chef's knife; this device operates on an entirely different principle. Instead of relying solely on a sharp edge and applied pressure, the Seattle Ultrasonics knife features a blade that oscillates at an astounding 30,000 times per second. This ultra-high frequency vibration effectively reduces friction between the blade and the material being cut, allowing it to glide through even the most challenging items with remarkable ease and precision. It's less about brute force and more about molecular disruption, creating microscopic air pockets that make the blade feel almost frictionless. At their booth, demonstrations included slicing through ripe tomatoes without deforming them, cutting warm, fresh bread without tearing, and even cleanly portioning delicate pastries and frozen desserts. The initial impression is one of effortless grace, transforming mundane kitchen tasks into something almost surgical.
Why It Matters
The implications of such technology extend far beyond just making prep work easier. For culinary professionals, this represents a significant leap forward in precision and consistency. Imagine perfectly uniform slices of fragile ingredients like fish roe, paper-thin carpaccio, or intricate garnishes that would typically require immense skill and a perfectly sharpened traditional blade. The reduced friction also means less degradation of delicate food structures, potentially enhancing presentation and even taste by preserving cellular integrity. In industrial settings, ultrasonic cutting has been used for years in applications ranging from plastics to textiles, known for its clean cuts and minimal waste. Bringing this level of precision to the consumer and professional kitchen could revolutionize food preparation, especially in patisseries, sushi restaurants, and fine dining establishments where presentation is paramount. Furthermore, the ability to cut through sticky or frozen foods without resistance could greatly improve efficiency and safety, reducing the effort and potential for slippage associated with conventional knives. It also opens doors for new culinary techniques, allowing chefs to achieve textures and cuts previously deemed impossible or extremely difficult.
What This Means For You
So, should you ditch your existing knife set and pre-order one of these buzzing beauties? The answer, as with most cutting-edge tech, is nuanced. The Seattle Ultrasonics knife is undeniably impressive, but it comes with a

Frequently Asked Questions
Q: What is an ultrasonic knife and how does it work?
A: An ultrasonic knife is a cutting tool that uses high-frequency vibrations to slice through materials. Unlike traditional knives that rely on sharpness and pressure, this knife's blade oscillates at an extremely rapid rate, typically tens of thousands of times per second. This rapid vibration reduces friction between the blade and the item being cut, allowing it to glide through with minimal resistance and often without deforming delicate structures. It effectively creates microscopic air pockets that enable a cleaner, more precise cut.
Q: What are the main advantages of using an ultrasonic knife over a traditional knife?
A: The primary advantages include unparalleled precision, significantly reduced friction, and the ability to make exceptionally clean cuts. This technology allows for slicing through very delicate foods like ripe tomatoes, soft cheeses, or pastries without crushing or tearing them. It also excels with sticky items, like nougat or certain baked goods, and even frozen foods, as the vibrations prevent material from adhering to the blade. This leads to less waste, improved presentation, and greater efficiency in food preparation.
Q: What specific foods or materials is the Seattle Ultrasonics knife best suited for?
A: The Seattle Ultrasonics knife is particularly well-suited for delicate produce such as ripe tomatoes, soft fruits, and leafy greens, where its precision prevents bruising. It's also ideal for baked goods like fresh bread, cakes, and pastries, ensuring clean slices without crumbling. Frozen desserts, chocolates, and sticky confectionery also benefit greatly from its low-friction cutting. Beyond the kitchen, similar ultrasonic technology is used in industrial settings for cutting textiles, plastics, and even composite materials, highlighting its versatility for various challenging substances.
Q: How much does the Seattle Ultrasonics knife cost, and is it worth the investment?
A: While exact pricing for the Seattle Ultrasonics knife was not officially released at CES 2026, it is anticipated to be a premium-priced product, aligning with the 'pricey blade' description. For the average home cook, it's likely a significant investment that might not justify the cost over a high-quality traditional knife set. However, for professional chefs, patissiers, or high-end culinary enthusiasts who prioritize absolute precision, efficiency, and the ability to handle challenging ingredients with ease, the enhanced capabilities and potential for new techniques could make it a worthwhile and valuable tool.
Q: Are there any safety concerns or special maintenance requirements for ultrasonic knives?
A: Like any advanced kitchen tool, ultrasonic knives come with specific safety and maintenance considerations. While the blade itself might not feel as 'sharp' in the traditional sense, the high-frequency vibrations generate heat and can cause serious injury if not handled correctly. Users must be trained on proper operation and safety protocols. In terms of maintenance, these devices typically require careful cleaning to avoid damaging the transducer unit, and specialized servicing might be necessary for calibration or repairs, differentiating them from simple blade sharpening.
Q: When and where will the Seattle Ultrasonics knife be available for purchase?
A: Based on its prominent showcasing at CES 2026, the Seattle Ultrasonics knife is expected to become available for purchase in the near future, likely in the months following the exhibition. While specific retail channels were not detailed, it's anticipated to be sold through specialty kitchenware retailers, high-end electronics stores, and potentially directly from Seattle Ultrasonics' official website. Interested consumers and professionals should keep an eye on product announcements and pre-order opportunities as the company moves towards a broader market launch.
