The Pigeon XL handy vegetable chopper container is made from high quality, food grade, BPA free plastic. Therefore, it is durable and capable of withstanding powerful chopping motions from the 5 sharp stainless steel blades. The Pigeon XL handy chopper container comes with a locking mechanism that keeps it firmly in place, so you do not have to worry about any slippage during use. It also comes with an anti-skid base to ensure it stays stable on any kitchen surface. The chopping mechanism has an easy mechanical pulley, which uses a spring and a thread. When the thread is pulled, the blades rotate. Depending on the force and the number of strokes, the vegetables can get finely chopped. The new addition of Whisker to the XL chopper made it more convenient
