The ChainRipper (tm) molded base and quality seam ripper is designed to split chain-pieced seams easily and conveniently. Because it uses a traditional seam ripper the ChainRipper (tm) can split the narrowest of chains (even a single stitch). The ripper can be removed from its base and used as a traditional seam ripper. When sheathed in its base the ChainRipper (tm) stands upright and can easily be located amidst a quilting project. Assorted Colors.
