I currently working at my four years at sushi high-end name of the sushi restaurant Nobu. I had two days a week to be ichiban at the sushi bar, the rest 3 days rotation with co-worker station. Here my set up for those days
Ichiban. Deba 180mm white# 2 Konosuke, Yanagi 300mm blue #1 and Nenohi 300mm sujihiki stainless
Yanagi for sashimi and nigiri, hosomaki, some roll except tempura roll. Sujhiki for tempura roll.
