"Seattle Ultrasonics C-200 knife review: a powered knife even a pro chef can love. 4 out of 5 stars"

"OMG this knife is incredible!!!!"

”It might just be the best new product I’ve tried all year.”

"It could genuinely alter the course of the industry forever."

"…The knife feels almost nonstick, as the vibrations — created by PZT-8 piezoelectric ceramic crystals — keep food from clinging to the blade"

"From stubborn tomato skins to tough root vegetables, the C-200 aims to turn kitchen prep from physical work into effortless precision."

"While Heimendinger’s knife still features a great piece of sharp Japanese san mai AUS-10 steel, it’s the handle that does the heavy lifting, with electronics that produce more than 40,000 vibrations per second, making the knife behave sharper than it physically is."

"The Seattle Ultrasonics C-200 chef's knife is an ultra-advanced piece of equipment for at-home chefs to incorporate into their preparation routine that will greatly reduce their effort, while also increasing their cutting capabilities."

"Seattle Ultrasonics has designed the world's first ultrasonic chef's knife for home cooks, dubbed the C–200. …despite only being announced this week, the knife has already garnered huge attention on social media."

"The C-200 pairs traditional craftsmanship with ultrasonic technology for smoother, cleaner cuts."
