Possibility of using a sharpener for sharpening scissors.

Technically, you can sharpen scissors on almost any sharpener — the design of their blades is not very different from knife ones. However, individual sharpeners may provide various design solutions that make it easier to work with scissors — for example, the ability to set the optimal sharpening angle or special mounts for such a tool. Therefore, for maximum convenience when working with scissors, you should still choose models where this function is directly stated.
