The Matfer 215030 Stainless-steel Heavy Duty Professional Quality Mandolin. It features a pusher knob made of plastic. The mandolin creates perfect vegetable slices. There is a reversible 38 prong julienne blade. Three cutting blades, glide plates and thickness adjustment mechanism are included. Levers allow for gradual thickness adjustments from paper-thin slices up to 1/2-Inch slices.
