You've got several choices...kind of depends on what you're after:http://www.chefknivestogo.com/misono4.html
A really great performer....steel is nice, but nothing super fancy. Grind is great, F&F good.http://www.chefknivestogo.com/masazumi4.html
Not all that different than the Misono, but a lot less money. Not as good of F&F, no kick ass dragon, not as great of a grind.http://www.chefknivestogo.com/mahccast24gy.html
Really similar to the Misono, but no kick ass dragon. http://www.chefknivestogo.com/masahiro.html
In that same league as the Masazumi.http://www.chefknivestogo.com/kielcagy24.html
Another good simple carbon.....slightly better than the cheaper versions.http://www.chefknivestogo.com/tkcsujihiki240.html
Another good option, although it's not true carbon....kind of a semi-stainless.
