ABSTRACT:
A floatable hand tool includes a shank having an inner wall formed with an axially extending through hole, and a tool tip mounted on an end of the shank and having an end portion provided with a protruding connecting rod inserted into the through hole of the shank so that the through hole of the shank forms a closed chamber. Thus, the floatable hand tool floats on the water level by the floating force produced by the closed chamber the through hole of the shank. In addition, the floatable hand tool floats on the water level, thereby preventing the floatable hand tool from being missed when falling into the water, and thereby facilitating a user operating the floatable hand tool in the water.
