This chopper delivers fast, consistent results each and everytime. It features an impressive 10.5-cup (2.6-quart) capacity.

The clear container lets you see the progress as you cut up cucumber, onion, zucchini, mushroom, tomato, squash etc. And because it requires no electricity, the Brieftons QuickPush Food Chopper can be used anywhere even when you are on the go.
It comes with 3 super sharp stainless steel blades for chopping, dicing, and slicing your way to a professionally prepared meal. They are made of heavy duty Japanese 420-grade hardened stainless steel, known not to rust or lose sharpness over time. Use them to make 12mm dices, 23mm dices, and 6mm-wide slices respectively. The blades have an extra large cutting surface, allowing you to process much more vegetables in one go compared to other chopper models.
The chopper is safer to use than chopping with a knife. The rubberized soft grip handle enhances leverage while the slip-proof base ensures total safety and stability as you slice and dice. When the top lid is closed, the blade is protected and safely tucked away from a busy chef's hands. It is also easy to clean. The product is dishwasher safe, and can be fully disassembled for easy cleaning on the top shelf of your dishwasher. The provided cleaning tool conveniently removes foodstuffs between the pusher teeth or blades.
Not only that, you can take comfort in the fact the results will be consistent everytime. The grid design of the blades ensure that your vegetables/fruits are cut to a certain size, which makes for beautiful presentations no matter how you cook or eat them.
