One of our favorite tools that works really well and takes up very little storage space. The blade is made from zirconium oxide, which is close in hardness to diamonds. Adjusts to four widths (.5 mm, 1.3 mm, 2 mm and 3 mm) just by turning the adjustment bar underneath. Stays sharp ten times longer than steel blades and is ideal for almost any veggie from zucchini, peppers, potatoes, apples, cucumbers and more. Enclosed hand guard keeps hands safe, but we recommend using a cut resistant glove sold separately. Lightweight and easy to clean. Dishwasher safe. 1" x 11" x 4". America’s Test Kitchen Highly Recommended.
