Ergonomic Potato Masher, 12 x 7 x 16.5cm H. Conventional mashers with their vertical grip can be awkward and inefficient to use. This ergonomic masher, however, features a D-shaped design with a non-slip grip that's much more comfortable to hold. It also transfers the downward force straight through the mashing plate, making short work of boiled potato. Fins on the edges of the handle allow you to scrape around the pan as you mash, ensuring you get every last lump.
