The handle of the most commonly used 21cm universal scissors is covered with a soft rubber layer on the inside.
The handle is suitable for both right and left hands.
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.
