Dull kitchen knives are among my biggest pet peeves (not to mention how dangerous they are), but I still have always struggled to keep up with my "knife maintenance" until I got this knife recently. Not only is the sharpener super easy to use, but the sharpening wheel is more effective than the traditional handheld sharpener that I was using before. Between the effectiveness and the ease of use, this knife/sharpener set is a complete gamechanger!
