Single-wristblade-handle single-hole deck-mount kitchen sink faucets have one wing-shaped handle that users pull toward or push away from themselves to start or stop the flow of water. Also called paddle handles, wristblade handles can be operated with the wrist. Because they do not need to be gripped to push or pull the handle, wristblade handles can be used by some individuals with disabilities. Single-hole deck-mount faucets combine the hot and cold water supplies to come out through a single spout, and they provide water for dishwashing, cooking, handwashing, and other tasks. They install into one hole on a flat surface, such as a sink or counter.
