This manual knife sharpener, designed with 40 years of expertise in the cutlery field, transforms knife sharpening into a hassle-free task even for beginners. Its clear usage guidelines and rational design guide users to sharpen safely and efficiently. Equipped with 6 adjustable angles (14°, 16°, 18°, 20°, 22°, 24°), the body marks angle recommendations for corresponding knife types. Simply rotate the adjustment dial to switch angles without guesswork. Just pull the blade through each slot unidirectionally a few times (no back-and-forth grinding), and the knife regains sharpness. The multifunctional system includes a tungsten steel coarse grinding slot, a ceramic fine grinding slot, and a dedicated slot for scissors, suitable for Japanese knives, Asian blades, professional kitchen knives, and even folding knives. The ergonomic handle ensures a firm grip, while dual silicone pads at the base secure the sharpener to the countertop, preventing sliding during operation. Its compact and lightweight design makes it ideal for home kitchens and outdoor camping, serving as a practical tool to maintain knife sharpness and a thoughtful gift for cooking enthusiasts.
