These new, sophisticated Sewing Embroidery Scissors are 3 7/8" long and are Stainless Steel with a beautiful Black Oxide finish also known as "Blackside" in the Singer Featherweight collecting world. They would make a perfect addition to any Blackside collection.
The blade or tips should be wiped clean after each use. The screw assembly or box joint should be oiled every few months (It is safe to just use a drop of your sewing machine oil.) If you cut paper with these it will dull the blade quickly so you want to use these for threads and fabric only.
