A flexible trowel has a compliant coupling between the handle and the blade. In the preferred embodiment, the handle is pivotally mounted to the elongated shaft extending from the planar blade for rotation in a plane generally perpendicular to the blade. The pivot pin extends transversely through a longitudinal recess in the handle. The handle is biased upward by a helical compression spring seated in a transverse passage in the handle and adjustably preloaded by a follower nut threaded on a bolt axially restrained in the end of the transverse passage by a retainer cap.
