ABSTRACT:
The combination wedge and notch trowel includes a reversible grip handle and an integrated wedge, for applying cement or adhesive to a substrate surface for installation of tiles. The ergonomically contoured reversible handle allows a user to use the notch trowel in a forward or backwards position with the same hand. The blade portion includes a notch pattern of conically shaped trapezoidal notches and large parabolic notches. The integrated wedge allows a user to use the wedge side of the trowel to pry up and remove tiles.
