Smith's 10-Second Knife & Scissors Sharpener features a "V" shaped knife sharpening slot with two crossed carbide blades. The carbide blades allow you to put a quick edge on your knife with just three or four strokes and are preset at a fixed sharpening angle for guaranteed results every time. The patented scissors sharpener is built into the handle and features a specially designed "floating" round ceramic rod. This floating rod conforms to the exact angle of your scissors during use and works on both left and right-handed scissors. Just three or four strokes through the sharpener will put the edge back on your household scissors.
