Titanium nitride is a reflective golden-colored ceramic material which reduces abrasion allowing the needle to stay sharper longer and ...
A free arm houses the machine's feeder and bobbin driver in a tubular arm-shaped bed, enabling material to be wrapped around the mechanism during sewing rather than simply resting on top of it. A free arm greatly simplifies sewing tasks like darning and hemming on delicate fabrics and difficult-to-reach seams—uses for which Elna was heavily ...
