All my scissors are sharper than a razor. In the 90s, an old seamstress learned how to sharpen them. I share the method in the comment

It is very important not to bring the scissors to the point where they become completely dull, but to constantly sharpen them as a preventive measure. To do this, it is not necessary to contact a specialist, but you can use improvised means.

I do it with a fine needle. This method is very effective. I take the needle and guide it to the edge of the scissor blades and as if I were opening the scissors with the needle, I guide it to the opening of the blades.

This needs to be done 6-7 times and the scissors will start cutting better than immediately.
