Come and see our amazing products. With our incredible 3-slot system, we're revolutionizing the art of knife sharpening! The 1st diamond sharpening rod repairs and straightens damaged blades before the 2nd slot sharpens to restore its V-shape. Finally, the 3rd slot fine tunes for a clean polish. Simply place the blade in each of the slots and gently pull the knife through a few times for fast, effective sharpening. Pls confirm with us about the packing info, stock color and exact production time before placing your order.
