Conventional immersion blenders are difficult to store due to their long handle and the right-angled position of the blending head. Delta solves this problem, as the head can be easily folded flat after use. Before use, the mashing head is simply locked in place with the small sliding ring on the handle. After use, you slide the sleeve back onto the handle and secure it at the base of the grip. Delta is not only easier to store but also more efficient to use. The curved mashing surface better conforms to the edges of the pan, allowing for more potatoes to be mashed with every movement of the potato masher. Suitable for non-stick cookware. Dishwasher safe.
