The Yes Company added a ton of practical features to the humble chopping board. The ChopBox has a built-in UV light that sanitizes both of its surfaces, addressing the biggest problem with the tool. It also has a slot so you can disinfect up to three knives at once using the light. A portion of the board also functions as a digital weighing scale and a timer, with a display that becomes invisible when not in use. Finally, it has two replaceable inset knife sharpeners.
