re: Are there any other knives that I need for my collection?

SFP.... if you want a good knife Japanese knife go to Chefknivestogo

You can get real hand made Japanese knives on that site for the same or less money than the Shun an other stuff in the stores. Get on the forum and follow their protocol of questions and you will get steered in the right direction for what you are looking for. My first gyuto from there was only $120. It’s bad arse...
