Let me narrow it down to 4 for you, because I've spent way too long looking at that site. Whatever the brand, you're looking for a 240 0r 270mm gyuto. If you're in to the traditional look, the JCK house brand
fu rin ka zan looks bad ass. carbon core clad with stainless. In a more traditionally western shape, the
carbonext comes highly rated. It's a next generation stainless, and holds an edge for a really long time. Amazing value.
Masamoto is one of the oldest knifemakers in Japan. can't go wrong with this carbon steel option. Lastlyl, I'm particular to
Blazens because I own one. It's a great workhorse knife. Stays sharp a long time, not too thin and not too thick.
