Increase your efficiency in the kitchen with the Chef Avenue V-Shape Slicer. Turn the dial knob on the handle to adjust the slicing thickness (1-3mm) and place the piece of fruit or vegetable you wish to slice in the food holder. Slide the food holder up and down the rails to slice the food. Caution: Blades are extremely sharp. Take extra caution not to touch the blades while operating the V-slicer, and always use the food holder at all times.
