Forever Silver Titanium 3D Universal Kitchen Knife 160mm Made in Japan GHB16-3DC [Product Overview] This single kitchen knife is all you need for home use. It's lightweight, rust-resistant, and features an antibacterial blade. The 3D patented blade shape allows you to cut food lightly and cleanly. ■The Sharpness of the 3D Knife■ When cutting into food, a regular knife uses a straight motion. However, the 3D knife has alternating straight and wavy sections. During the straight motion, the unevenness of the wavy sections creates a diagonal movement, eliminating the pressure between the blade and the food, allowing you to cut food lightly and cleanly. Although it is new and unused, it has been stored at home, so please purchase it if you don't mind. If you have any questions, please feel free to ask. I will do my best to ensure a smooth transaction, so thank you.
