Jiffy V- Knife & Scissors ener features a "V" shaped knife ening 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 ening angle for results every time. The carbide blades in the knife ener are reversible and replaceable for long-lasting use. The patented scissors ener 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 ener will put the edge back on your household scissors.
