This is a manual hand-press vegetable and onion chopper.
It is designed to quickly and easily chop or dice vegetables, garlic, nuts, herbs, and more.
Operation involves placing food in the base and pressing down on the top handle with your palm.
The sharp, stainless steel blades rotate with each press to ensure thorough cutting.
It is typically made from food-grade plastic and stainless steel, and is often dishwasher safe.
The design allows food to be chopped in an enclosed container, which can help contain odors like onion and garlic.
