Has 2 spatula edges that scrape the sides and bottom of the bowl, resulting in thorough ingredient incorporation. Compared to our flat beater, the double flex edge beater increases contact with the bowl and reduces the need to stop and manually scrape stray ingredients clinging to the sides. For multitasking: from cakes to cookies, to frostings, to mashed potatoes, to cheesecake. Top rack dishwasher-safe.
