In separate news, while I have a Santoku and I like the idea of it and use it from time to time, I had not found anything that actually needed a Santoku, as opposed to being slightly easier. Until today. Cutting freshly dug potatoes, the sort that are as brittle as a brittle thing for a day or so. My normal knives are all too thick and split rather than cut, even the six inch, the santoku sliced like a ninja.
