Bodum 10570 is a kitchen appliance designed to help you quickly and easily chop herbs. It consists of a transparent cup with rotation aids built into its base, and a two-section lid. The lower section of the lid holds a hardened stainless steel knife assembly, while the upper section provides a comfortable grip for turning and rotating the lid.

To use the Bodum 10570, simply remove the lid, add your herbs to the cup, and replace the lid. Then, take the appliance in both hands and rotate the cup and lid back and forth in opposite directions until the herbs have reached the desired fineness. You can shake the cup while rotating it to help distribute the herbs evenly. Once the herbs are chopped to your liking, simply remove the lid and empty the contents into a saucepan or bowl.
