  • Mason's hand trowel
    Patent number: 7818844
    Abstract: A hand trowel is provided with upstanding side and rear walls to prevent cement or grout from sliding off when scooped from a container. The sidewalls of the trowel taper to the front edge of the trowel so that no barrier is created to prevent the front edge from being utilized as a “finishing” edge. A handle extends from the rear wall of the trowel. The handle is provided with ergonomic indentations and the front edge is slanted to allow use by either a right- or a left-handed person.
