OXO potato masher
From the manufacturer: This innovative potato masher lets you achieve smooth mashed potatoes with less pressure on your hands. The wide, soft, horizontal handle pushes straight down, cushioning your grip and absorbing pressure. The stainless steel plate with the close-meshed grid produces mashed potatoes without lumps. It's also great for mashing carrots or other root vegetables, or for homemade baby food made from mashed apples or bananas.
