These every-day, versatile cutting tools have an advanced ceramic blade that is close in hardness to diamond. This unique blade will stay sharper 10X longer than any steel blade. It is totally impervious to acids, juices, oils, salts or other elements. As a result, it will never alter the taste, smell or appearance of food and it will never rust or corrode. It's lightweight and easy to use with a one-blade thickness. You'll find the slicers useful for everything from cutting vegetables for a stir-fry or potato chips to slicing apples for a tart. The double-edged straight slicer creates wide paper-thin slices of apples and other fruits or vegetables. A hand guard keeps your fingers out of harm's way.
