Abstract
A hand tool for rolling an O-ring under a downward pressure into a slot opening is described. The hand tool is constructed by a tool body that has an arcuate top surface adapted for gripping by a human hand and a planar bottom surface. The planar bottom surface of the tool body is provided with a cavity adapted for receiving a pair of rotatable balls mounted juxtaposed to each other. The pair of rotatable balls are mounted on a shaft through a center aperture of the balls in the cavity in such a way that only less than half of the spherical surface of the balls is protruding beyond the planar bottom surface of the tool body.
