I always loved these long Tadatsuna petties, they are so elegant. At one point I asked Moritaka to make something similar for me. What I ended up with is a very cool knife that is a mix between a petty and a salmon knife, ultra thin and narrow. I think that means I still need a petty... But I do have a Blazen petty that is a bit shorter, but I really like it for a Western handled small utility knife. A small Carter funayuki also works well as a petty, and you can get them in different styles. And I admit that I sometimes reach for a honesuki when I need something in that size but sturdier, for cutting off a chunk of parmesan etc.
