ABSTRACT:
An improved cement finishing hand tool having a handle member with a gripper shaft, a proximal end and a distal end, the distal end being substantially downwardly angled so as to be removably engaged with an upper surface of a removable blade member. The removable blade member is interchangeably secured to the handle member which is structured to independently vibrate resulting in the translation of the vibration from the handle member through the blade member. This vibration facilitates the production of a corresponding desired finish as the lower surface of the blade member is passed over wet cement during the initial and final stage finishing procedures.
