Twisted Tornado Crimp®, Bella Flamed Copper. Packs of 25.
No special crimp tool needed, use your tapered end chain nose pliers. The manufacturer states these can be used with stringing wire (.014 Soft Flex up to .018 Beadalon, .019 Soft Touch or Soft Flex.) They have designed these to be very snug, so be advised to cut the beading wire at an angle before pushing the wire through. This is very secure crimp, and a very nice look compared to standard crimps. To use, just cut your beading wire on an angle to give it a sharp point and run it through the crimp and back again. Make sure your wire sits side by side in the crimp. That way the crimp presses down on both wires at the same time. Crimp it with a pair of flat chain nose pliers. Turn it over again and press hard again.
