About the Shape - Under utilized in the western kitchen, the nakiri’s flat blade is meant for the push/pull chopping of vegetables. Since the entire flat edge of the knife ktouches the cutting board at once, you wont be turning the vegetable into an 'accordion', still connected like a paper doll after you've cut them. The added weight of the blade allow it to fall through food more easily while you chop, so the knife does more of the work for you! Masakage nakiris are made taller than the average nakiri so they last longer and work better for folks with large hands.
About Masakage Zero - The Masakage Zero line is top notch, a high performance knife combining unbelievable sharpness and pure hotness. These blades make people stop in their tracks to catch a second look, with a handle of Ironwood (one of the world's hardest woods), pinned with a mosaic in the shape of a chrysanthemum — the Zero plays second fiddle to no knife.
