Furthermore, it’s 【non-absorbent】, so you don’t need to soak it in water for 5-10 minutes before use. Simply lightly wetting the surface right before use makes it incredibly convenient to start working immediately. It also boasts significantly improved durability compared to traditional sharpening stones. ・【Extra-Large Size & Exceptional Ease of Use】Significantly upgraded from the conventional 180x60mm size to a large 210x70x22mm size. Compared to smaller sharpening stones, the blade is easier to stabilize, and the stability when applying the knife has been dramatically improved. The wider sharpening surface greatly increases sharpening efficiency, making it ideal for sharpening not only ordinary knives but also long knives and large knives. ・【Non-Slip Rubber Base & Safety Design】Includes a new silicone non-slip rubber base. By expanding the contact area, it’s difficult to slip when used as a sharpening stand, and it exhibits excellent stability. The sharpening stone is securely fixed even when applying force, preventing unexpected injuries or accidents when sharpening knives and blades, even for beginners. ・【Suitable for All Blades & Extended Lifespan】Compatible with a wide range of knives, including Western-style knives such as Santoku and Chef’s knives, as well as Japanese knives such as Deba, Yanagiba, and Sashimi knives, and Chinese cleavers, and scissors. It sharpens steel and stainless steel blades to a razor edge. Regular maintenance can significantly extend the lifespan of your favorite knives and maintain an exceptional sharpness like new for a long time.
