That’s not necessary with an ultrasonic knife and would generally be a waste of time. The vibrations take the place of needing to slice, rather than chop. This

That’s not necessary with an ultrasonic knife and would generally be a waste of time. The vibrations take the place of needing to slice, rather than chop. This knife is not meant to be used like a normal chef’s knife. I’d still never get one because I love my knives (and zen out hard when sharpening for an hour or two), but the push is literally the goal here.
