The unitary, hand held tool is comprised of a body portion having first and second ends. The body has a length dimension which is sufficient to span the distance between the centers of at least three outer link plates of a multi-link roller chain. The first and second fixed prongs emanate from, are integral with the body portion, and are preferably angled towards one another. The fixed prong adjacent to the first end of the body portion, and the second fixed prong adjacent to the second end of the body portion extend from the linear body portion in substantially the same plane. The prongs are dimensioned to fit into the openings between spaced apart rollers of a multi-link roller chain, and long enough to secure such spaced apart rollers when fit into such openings. In preferred embodiments there is a curved surface between the first fixed prong and the body portion and also a curved surface between the second fixed prong and the body portion, each curved surface having an inner diameter at least equal to or greater than the outer diameter of the rollers of the multi-link roller chain with which it is to be used, to thereby serve to seat the rollers within the curved surfaces.
