We found the perfectly minimalist, manual kitchen knife sharpener that gives you the simplest, most durable, no-batteries-required solution to keeping all your straight-edge knives in tip-top chopping and slicing condition. Unlike the old-school manual methods using a whetstone or sharpening rod, you won’t need to put any time or effort into honing your knife-sharpening skills. It’s as easy as 1-2-3. Literally. Plus, unlike the regular 2-slot products, ours is a 3-slot knife sharpener, with coarse and medium Tungsten carbide blades angled perfectly to shape your knife to a hollow finish, and a fine ceramic honing stage to put that perfect a hollow edge finish and polish on your blade. Most days, all you’ll need is a couple of glides through the ceramic sharpener to maintain that razor-sharpness. The suction base securely attaches to the solid, smooth surface of your benchtop, keeping it steady while you sharpen single-handedly! No need to hold with your other hand, and no need to clean away filings every time, it’ll catch those in the screwable base for emptying later.
