I recommend Kiwis all the time to people who want to spend less than 10 bucks on a knife, and I have used them many times. Kiwis work well (aka move through food well) because they are crazy thin. That’s it. They are a great argument for the value of a laser, which perhaps more knifemakers and users could benefit from learning. They are like a piece of aluminum foil with a handle on it, you could literally bend them in half. Because of that, even when dull they will split food fairly efficiently. If someone’s only concern is an inexpensive and easy solution to cutting food, they are a fine option. They are not uncomfortable, they are not hideous looking, they are easy to maintain. They could probably be considered “best of class”. But that class is the “I don’t want to spend more than 10 bucks on a knife” class, which is mostly full of weird serrations, rainbow hued cuisinarts, and cheap stamped plastic handled garbage that dulls quickly. Using one isn’t a luxury or high performance experience, and do not generally lead one to “enjoy” their experience or their tools more. If that’s not an issue for you, then they are a great choice. Their flexiness, light weight, and smaller sizes and shapes make them a no go FOR ME, but are great for some. Would not trade my experiences.
