The GS-4 is Global's small version of the Deba Bocho knife, a small version of the G-7 Deba, a Japanese style kitchen knife used to cut mostly fish but also meat. This knife has the traditional Japanese one sided grind so is not suitable for Western style preparation. It can be used for cutting, filleting and slicing smaller fish. A perfect small utility knife for Japanese chefs who use a larger Sashimi or Deba knife and need something for lighter work.
