If you need scissors with a non-stick coating, choose a black blade. Non-Stick coated scissors do not form a sticky layer of glue on the blades when cutting tapes and other materials with a sticky layer of glue.
KL24 recommends:
* occasionally put a drop of oil between the screws of the scissors - this way your scissors will cut longer and better.
* if there is a notch cut into the blade of the scissors, have it sharpened before the marks wear into the sides of the scissors,
* have your scissors sharpened only by a specialist.
