This easy-to-use manual knife sharpener from KitchenIQ (formerly Edgeware) allows you to select the correct sharpening angle of both the coarse and the sharpening slots at the same time by pushing and turning the knob. The knife sharpener offers more than 2 angles and adjusts from 14° to 24° per side of the knife. It sharpens Asian, straight, and serrated knives. The manual knife sharpener allows you to turn your older knives to their factory produced sharpening angle and fix damaged and dull knives by using the coarse sharpening slot. The fine slot is perfect for polishing the edge of an already sharp knife or for everyday maintenance. The KitchenIQ knife sharpener has a compact size to ensure it will fit in your drawer.
