ABSTRACT:
A semi-solid jewelry chain includes a plurality of generally C-shaped links which links are woven into each other. The jewelry rope chain is made with a cutting tool, which includes an extended blade member having a rounded groove therein with a nesting surface conforming to the contours of the material to be cut, such as a jewelry rope chain wire, to form a link, which link may be preferably a semi-solid link, which link has an interior cavity. The semi-solid rope chain has a weight ratio in relation to solid rope chain, wherein the weight ratio of semi-solid chain to solid chain, expressed as a per cent, is from about 50.1% to about 99.9%.
