Preparing avocados can be difficult, messy and even hazardous if using sharp knives. The handy GoAvocado 3-in-1 Green Avocado Tool by Joseph Joseph though, provides the complete avocado preparation tool, allowing you to open, de-stone, scoop and slice all in one. It features a fold-out plastic blade, a stainless-steel pitter, a curved slicing head and an ergonomic, soft grip handle.
