I’m interested option hear why people are saying less than 40. Perhaps I’m wrong. It if I want a super small task I grab a paring knife. So that I would want in like a sub 36mm height.
But if I want a longer blade but not a full gyuto size then I feel like 40 is a good height compared to the length.
So for example I had a Shibata ko bunka in like 130 x 40 (I think) and it was fine but using the 180 x40 petty, the bunka seems less convenient in that height. Where as when I use my 70 x20 mm paring knife it is perfect for strawberries.
