Abstract: A water-wiper apparatus has a handle having a height, width, and length with a substantially oval shape in cross-section orthogonal to the length, a major axis of the oval shape in the direction of the height, the handle formed of a rigid or semi-rigid material, a first engagement interface along the length of the handle in a region bisected by the major axis, the engagement interface comprising a channel having a shape and a first width and an opening of a second width less than the first width to the outside of the handle, and a wiper blade of the length of the handle, formed of a flexible material and having a second engagement interface shaped to engage the first engagement interface, engaging the wiper blade with the handle, the wiper blade having a curved side in cross section from the handle to a tip end of a wiper leg away from the handle, the curve of the side having a radius of from one-half inch to one-and-one-half inches.
