Sharp, sharper, sharpest - those are the three easy steps to getting old, blunt knives like new again. And this 3-Stage Sharpener makes it so easy. Stage 1: Pull the knife through the diamond surface slot - this grinds a keen edge on the dullest blade. Stage 2: Repeat the process in the tungsten steel slot. Now the blade is getting seriously sharp. Stage 3: Finally, draw the knife through the thrid, fine ceramic stone slot. This hones the blade (like an old-fashioned razor strop) and polishes it to razor like finish. Very easy to operate - thanks to the soft-grip ergonomic handle - suitable for both right and left-handed use, it will have blunt old blades sharp as new before you can say 'knife'. | Easylife 3-Stage Knife Sharpener in Grey, Ceramic
