Materials and Design

Your onion dicer should be practical and easily fit in your kitchen. For a manual chopper, ensure that it has a good grip and easy-to-use pull handles to prevent strain. You want to ensure that minimal effort is required when chopping onions.

Additionally, the sharp blades should be durable, and resistant to corrosion/rust. Stainless steel blades will generate a cleaner cut and will work more efficiently.

Pay attention to how you cook. Are you dicing onions for meal prep for the week or using them for a single meal? This will determine what capacity you need.
