“Hello tech enthusiasts and fellow foodies! Every year’s CES (Consumer Electronics Show) always opens our eyes, and this year is no exception. But to be honest, after seeing countless walking robots and self-driving cars, the product that made everyone ‘tremble’ this year is actually… a kitchen knife?That’s right, this ‘Ultrasonic Cutter’ launched by Seattle Ultrasonics was the star of the show. This knife claims to vibrate up to 30,000 times per second—doesn’t that sound a bit like a lightsaber from a sci-fi movie? Today, we’re going to talk about this ‘expensive’ divine blade and see if it is truly capable or just a marketing gimmick.
⚡️ Technical Core: The Ultimate Frequency of 30,000 Times Per Second
The core technology of this ultrasonic knife lies in its built-in high-frequency transducer. Simply put, it doesn’t rely on the mechanical force of ‘sawing’ or ‘cutting’, but uses the energy generated by high-frequency vibrations to instantly ‘shake’ apart the binding forces between the object’s molecules.
- Physical Highlight: Because it vibrates 30,000 times per second, the friction between the blade and the food is reduced almost to zero. This means that when you are cutting extremely difficult ingredients (such as hot bread fresh out of the oven, soft-textured tomatoes, or clearly layered mille-feuille), the tragedies of ‘squashing’ or ‘tearing’ will no longer occur.
- Precision: On-site tests found that the cut surfaces are as smooth as a mirror, completely eliminating the need for any back-and-forth sawing motion; it truly feels like ‘lifting something heavy as if it were light.’
🔪 Practical Test: A ‘God-tier Teammate’ or ‘Showy Fluff’?
The author personally tried this knife at CES, and the feeling can only be described as ‘silky smooth.’ If you used to break a sweat cutting frozen meat or extremely sticky cheese, this knife is simply a savior. It’s as if an invisible force is guiding the blade to automatically ‘glide’ through the ingredients.However, this knife isn’t without its flaws. First, it is a corded design (to ensure stable high-frequency power), which can be a bit cumbersome in a kitchen that demands efficiency. Furthermore, it emits a very high-pitched buzzing sound when operating. While it’s not exactly piercing, it might take some time for those sensitive to sound to get used to it.Editor’s Comment: This feeling is much like upgrading from a traditional broom to a top-tier vacuum cleaner. While it’s packed with technology, you can’t help but wonder: Do I really need such high-tech gear to handle a sandwich?
💰 Price Barrier: You Need Deep Pockets to be a ‘Master Chef’
When discussing the downsides of this knife, besides the power requirements, what will definitely ‘drain your wallet’ is its price. Although the official final pricing hasn’t been released, based on reports from the scene, the positioning of this knife is clearly not for the average housewife to cut vegetables, but is aimed at professional chefs and top-tier tech enthusiasts.If you only cook instant noodles occasionally, this knife might be a bit ‘overkill’ for you; but if you have OCD about food cross-sections or are someone who pursues the aesthetics of an ultimate lifestyle, this is definitely the most ‘highly anticipated’ kitchen luxury of the year.
🧐 Summary: How Does Technology Change Our Taste Buds?
The ultrasonic knife launched by Seattle Ultrasonics this time, though its price might make people hesitate, demonstrates how technology can perform a ‘dimensionality reduction strike’ on traditional industries. It’s not just a knife, but a pursuit of ‘precision living.’
- The Significance: It narrows the gap between professional and amateur. Even if your knife skills are average, you can achieve Michelin-level results with this knife.
- Market Perspective: I believe this type of product will first become popular in high-end catering circles. Once the technology matures and costs decrease, perhaps every home will have one of these ‘vibrating’ gadgets in the future.
Finally, do you think this knife is ‘truly amazing’ or just a ‘tax on intelligence’? If the price is under 10,000 TWD, would you consider buying it? Feel free to leave a comment below and tell us your thoughts!
